fnctl: f_modown should call write_lock_irqsave/restore

commit b04da8bfdfbbd79544cab2fadfdc12e87eb01600 upstream.

Commit 703625118069f9f8960d356676662d3db5a9d116 exposed that f_modown()
should call write_lock_irqsave instead of just write_lock_irq so that
because a caller could have a spinlock held and it would not be good to
renable interrupts.
