[PATCH -next] fanotify: remove variable set but not used

[Yang Li]

The code that uses the pointer info has been removed in
'https://lore.kernel.org/all/20211129201537.1932819-11-amir73il@xxxxxxxxx/'
and fanotify_event_info() doesn't change 'event', so the declaration and 
assignment of info can be removed.

Eliminate the following clang warning:
fs/notify/fanotify/fanotify_user.c:161:24: warning: variable ‘info’ set
but not used
