[PATCH 4/6] xfs: Set BH_New for allocated DAX blocks in __xfs_get_blocks()

[Jan Kara <jack@suse.cz>]

So far we did not set BH_New for newly allocated blocks for DAX inodes
in __xfs_get_blocks() because we wanted to avoid zeroing done in generic
DAX code which was racy. Now the zeroing is gone so we can remove this
workaround and return BH_New for newly allocated blocks. DAX will use this
information to properly update mappings of the file.
