kgdb,x86: remove redundant test
NILFS2 supports the following mount options:
(*) == default
-barrier=on(*) This enables/disables barriers. barrier=off disables
- it, barrier=on enables it.
+nobarrier Disables barriers.
errors=continue(*) Keep going on a filesystem error.
errors=remount-ro Remount the filesystem read-only on an error.
errors=panic Panic and halt the machine if an error occurs.
blocks. That means, it is guaranteed that no
overtaking of events occurs in the recovered file
system after a crash.
+norecovery Disable recovery of the filesystem on mount.
+ This disables every write access on the device for
+ read-only mounts or snapshots. This option will fail
+ for r/w mounts on an unclean volume.
