TAKE 966562 - XFS should not be looking at filp reference counts

[David Chinner]

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.
