ANDROID: Remove out-of-tree difference in fsnotify.h

Browse Source 
commit dd5c936967 ("Merge 7e63420847 ("Merge tag 'acpi-5.7-rc1-2' of
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm") into
android-mainline") introduced a difference to the upstream tree by
discarding all changes done in include/linux/fsnotify.h.

This can be seen when comparing the difference that should have been
introduced by the merge (diff between the upstream merges)

  $ git diff 5364abc57993..7e63420847ae -- include/linux/fsnotify.h
    1 file changed, 58 insertions(+), 80 deletions(-)

... and the actual difference introduced ...

  $ git diff dd5c9369672e^1..dd5c9369672e -- include/linux/fsnotify.h
    <empty>

This reverts the out-of-tree difference.
