cifs: remove unused function cifs_oplock_break_wait

Commit 743162013d40 ("sched: Remove proliferation of wait_on_bit() action
functions") has removed the call to cifs_oplock_break_wait, making this
function unused; remove it.

This fixes the following compilation warning:

  fs/cifs/misc.c:578:1: warning: ‘cifs_oplock_break_wait’ defined but not used [-Wunused-function]
