Typo in bash-nvme-completion.sh

[nbarrios1337]

Behavior

When using tab autocompletion for nvme get (i.e. nvme get<tab><tab>), I get the following:

get_feature    get-log    get-ns-id 

However, man nvme and nvme help list the "get feature" subcommand as get-feature.

Trying to use nvme get_feature results in the same usage dialog as nvme help, instead of the subcommand-specific:

get-feature: Invalid argument
Usage: nvme get-feature <device> [OPTIONS]

Read operating parameters of the specified controller. Operating parameters
are grouped and identified by Feature Identifiers; each Feature Identifier
contains one or more attributes that may affect behaviour of the feature.
Each Feature has three possible settings: default, saveable, and current. If
a Feature is saveable, it may be modified by set-feature. Default values are
vendor-specific and not changeable. Use set-feature to change saveable
Features.

Options:
  [  --namespace-id=<NUM>, -n <NUM> ]   --- identifier of desired namespace
  [  --feature-id=<NUM>, -f <NUM> ]     --- feature identifier
  [  --sel=<NUM>, -s <NUM> ]            --- [0-3]:
                                            current/default/saved/supported
  [  --data-len=<NUM>, -l <NUM> ]       --- buffer len if data is returned
                                            through host memory buffer
  [  --raw-binary, -b ]                 --- show infos in binary format
  [  --cdw11=<NUM>, -c <NUM> ]          --- dword 11 for interrupt vector
                                            config
  [  --human-readable, -H ]             --- show infos in readable format

Autocompleting nvme get-feature (i.e. nvme get-feature<space><tab><tab>) works as intended, showing (in my case):

-b                /dev/nvme0n1p1    --feature-id=     -l                --sel=
--cdw11=          /dev/nvme0n1p2    -h                -n                
--data-len=       /dev/nvme0n1p3    -H                --namespace-id=   
/dev/nvme0        /dev/nvme0n1p4    --help            --raw-binary      
/dev/nvme0n1      -f                --human-readable  -s   

Expected Behavior

Autocompleting nvme get should result in: get-feature get-log get-ns-id, matching the rest of nvme-cli's documentation and help dialogs.
