fs/locks: change all *_conflict() functions to return bool.
posix_locks_conflict() and flock_locks_conflict() both return int.
leases_conflict() returns bool.
This inconsistency will cause problems for the next patch if not
fixed.
So change posix_locks_conflict() and flock_locks_conflict() to return
bool.
Also change the locks_conflict() helper.
And convert some
return (foo);
to
return foo;
