On FreeBSD, pthread mutex, cond, and spinlocks allocate memory. On
Linux-based systems, these calls do not allocate memory. So there was a
safe assumption that the ofed RDMA verb calls do not need to explicitly
destroy the pthread locks. This assumption is false on FreeBSD. So let
us rearrange the code to cleanup the pthread locks.

Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

much every T5 card that does _not_ have "-SO" in its name is RDMA
capable).
This plugs into the OFED verbs framework and allows userspace RDMA
applications to work over T5 RNICs. Tested with rping.
