HV: declare and export sharing mode's vdev functions as global instead of static local

Export the following functions as global instead of static so that they can be
called/referred outside of the files where they are declared:
vmsi_init
vmsi_cfgread
vmsi_cfgwrite
vmsi_deinit
vmsix_init
vmsix_cfgread
vmsix_cfgwrite
vmsix_deinit

This is in preparation for removal of the sharing modes vdev ops, and call them
directly instead.
