fanotify: Allow copying of file handle to userspace
When file handle is embedded inside fanotify_event and usercopy checks
are enabled, we get a warning like:
Bad or missing usercopy whitelist? Kernel memory exposure attempt detected
from SLAB object 'fanotify_event' (offset 40, size 8)!
WARNING: CPU: 1 PID: 7649 at mm/usercopy.c:78 usercopy_warn+0xeb/0x110
mm/usercopy.c:78
Annotate handling in fanotify_event properly to mark copying it to
userspace is fine.
