Precedence: bulk

Looks like during merging the bulk POLL* -> EPOLL* replacement
missed the patch
'commit af336cabe083 ("mei: limit the number of queued writes")'

Fix sparse warning:
drivers/misc/mei/main.c:602:13: warning: restricted __poll_t degrades to integer
drivers/misc/mei/main.c:605:30: warning: invalid assignment: |=
drivers/misc/mei/main.c:605:30:    left side has type restricted __poll_t
drivers/misc/mei/main.c:605:30:    right side has type int
