sched: Convert the only user of cond_resched_bkl to use cond_resched()

fs/locks.c:flock_lock_file() is the only user of
cond_resched_bkl()

This helper doesn't do anything more than cond_resched(). The
latter naming is enough to explain that we are rescheduling if
needed.

The bkl suffix suggests another semantics but it's actually a
synonym of cond_resched().
