If we're in mpt_wait_req and the command times out,

Browse source 
mark it as timed out. Don't try and free the config
request for read_cfg_header that times out because
it's still active. Put in code for the config reply
handler that will then free up timed out requests.

Fix the FC_PRIMITIVE_SEND completion to not try
and free a command twice. Dunno how this possibly
could have been working for awhile.
