Subject: [PATCH] exofs: exofs_file_fsync and exofs_file_flush correctness

As per Christoph advise: no need to call filemap_write_and_wait().
In exofs all metadata is at the inode so just writing the inode is
all is needed. ->fsync implies this must be done synchronously.

But now exofs_file_fsync can not be used by exofs_file_flush.
vfs_fsync() should do that job correctly.

FIXME: remove the sb_sync and fix that sb_update better.
