Fix CTL GET EVENT STATUS NOTIFICATION valid bits

Linux as an initiator periodically sends the following to SCSI cdrom
devices: 4a 01 00 00 10 00 00 00 08 00

According to the ctl_cmd_entry for this command this is invalid which
leads to a lot of failed SCSI commands.

The mask in this commit is based off of the t10 spec available here:
https://www.t10.org/ftp/t10/document.97/97-108r0.pdf

And @bsdimp's research.

This solves the issue with Linux initiators.
