file: add fput and file_ref_put routines optimized for use when closing a fd
Vast majority of the time closing a file descriptor also operates on the
last reference, where a regular fput usage will result in 2 atomics.
This can be changed to only suffer 1.
See commentary above file_ref_put_close() for more information.
