Christoph Hellwig 489a150f64 xfs: factor duplicate code in xfs_alloc_ag_vextent_near into a helper ...

Add a new xfs_alloc_find_best_extent that does a forward/backward
search in the allocation btree.  That code previously was existed
two times in xfs_alloc_ag_vextent_near, once for each search
direction.

Based on an earlier patch from Dave Chinner.
