fanotify: fix incorrect fmode_t casts

Fixes sparce warnings:
fs/notify/fanotify/fanotify_user.c:267:63: sparse:
 warning: restricted fmode_t degrades to integer
fs/notify/fanotify/fanotify_user.c:1351:28: sparse:
 warning: restricted fmode_t degrades to integer

FMODE_NONTIFY have bitwise fmode_t type and requires __force attribute
for any casts.
