xfs: simplify xfs_map_at_offset
Move the buffer locking into the callers as they need to do it
wether they call xfs_map_at_offset or not. Remove the b_bdev
assignment, which is already done by get_blocks. Remove the
duplicate extent type asserts in xfs_convert_page just before
calling xfs_map_at_offset.
