xfs: BMAPX shouldn't barf on inline-format directories
commit 6eadbf4c8b
upstream.
When we're fulfilling a BMAPX request, jump out early if the data fork
is in local format. This prevents us from hitting a debugging check in
bmapi_read and barfing errors back to userspace. The on-disk extent
count check later isn't sufficient for IF_DELALLOC mode because da
extents are in memory and not on disk.
