xfs: check that dir block entries don't off the end of the buffer

Source kernel commit: 6215894e11de224183c89b001f5363912442b489

When we're checking the entries in a directory buffer, make sure that
the entry length doesn't push us off the end of the buffer.  Found via
xfs/388 writing ones to the length fields.
