io-wq: io_wqe_run_queue() doesn't need to use list_empty_careful()

mainline inclusion
from mainline-91d666ea undefined
commit 91d666ea
category: feature
bugzilla: https://bugzilla.openeuler.org/show_bug.cgi?id=27
CVE: NA
---------------------------

We hold the wqe lock at this point (which is also annotated), so there's
no need to use the careful variant of list_empty().
