The use of kmap() is being deprecated in favor of kmap_local_page(). With
kmap_local_page(), the mapping is per thread, CPU local and not globally
visible.
The usage of kmap_local_page() in fs/ufs is pre-thread, therefore replace
kmap() / kunmap() calls with kmap_local_page() / kunmap_local().
kunmap_local() requires the mapping address, so return that address from
ufs_get_page() to be used in ufs_put_page().
These changes are essentially ported from fs/ext2 and relie largely on
commit 782b76d7abdf ("fs/ext2: Replace kmap() with kmap_local_page()").
