xfs: simplify xfs_vm_writepage
The writepage implementation in XFS still tries to deal with dirty but
unmapped buffers which used to caused by writes through shared mmaps. Since
the introduction of ->page_mkwrite these can't happen anymore, so remove the
code dealing with them.
Note that the all_bh variable which causes us to start I/O on all buffers on
the pages was controlled by the count of unmapped buffers, which also
included those not actually dirty. It's now unconditionally initialized to
0 but set to 1 for the case of small file size extensions. It probably can
be removed entirely, but that's left for another patch.
