[XFS] XFS should not be looking at filp reference counts
A check for file_count is always a bad idea. Linux has the ->release method to deal with cleanups on last close and ->flush is only for the very rare case where we want to perform an operation on every drop of a reference to a file struct. This patch gets rid of vop_close and surrounding code in favour of simply doing the page flushing from ->release.
