xfs: verify inline directory data forks

Source kernel commit: 630a04e79dd41ff746b545d4fc052e0abb836120

When we're reading or writing the data fork of an inline directory,
check the contents to make sure we're not overflowing buffers or eating
garbage data.  xfs/348 corrupts an inline symlink into an inline
directory, triggering a buffer overflow bug.
