ext4, dax: add ext4_bmap to ext4_dax_aops
commit 94dbb63117e82253c9592816aa4465f0a9c94850 upstream.
Ext4 mount path calls .bmap to the journal inode. This currently
works for the DAX mount case because ext4_iget() always set
'ext4_da_aops' to any regular files.
In preparation to fix ext4_iget() to set 'ext4_dax_aops' for ext4
DAX files, add ext4_bmap() to 'ext4_dax_aops', since bmap works for
DAX inodes.
Fixes: 5f0663bb4a64 ("ext4, dax: introduce ext4_dax_aops")
