Konstantin Khlebnikov 80c1fe9026 mm/filemap.c: remove redundant cache invalidation after async direct-io write
generic_file_direct_write() invalidates cache at entry.  Second time this
should be done when request completes.  But this function calls second
invalidation at exit unconditionally even for async requests.

This patch skips second invalidation for async requests (-EIOCBQUEUED).
