Currently btrfs_should_throttle_delayed_refs() returns 1 or 2 in case the
delayed refs should be throttled, however the only caller (inode eviction
and truncation path) does not care about those two different conditions,
it treats the return value as a boolean. This allows us to remove one of
the conditions in btrfs_should_throttle_delayed_refs() and change its
return value from 'int' to 'bool'. So just do that.
