LU-443 LNet: Only squawk when md->start is NULL on non-zero length

Only squawk when md->start is NULL on non-zero length.
The md->start == NULL check prevents anyone from creating a ME/MD
with no buffer. These are used as backstop buffers to generate events
when traffic has exceeded the local buffer space.
See Oracle bug 21103 attachment 32922.
