[PATCH] scsi: fnic: return error if vmalloc failed

[Artem Chernyshev]

In fnic_init_module() exists redundant check for return value
from fnic_debugfs_init(), because at moment it only can
return zero. It make sense to process theoretical vmalloc failure.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

Fixes: 9730ddfb123d ("scsi: fnic: remove redundant assignment of variable rc")
