Each VF employees a lock that's supposed to serialize its usage of the
HW channel for communication with its PF, but the critical section is
ill-defined:
- VFs currently release the lock whenever the PF response arrives,
prior to actually processing the reply buffer [which was also supposed
to have been protected by same lock].
- The lock would be released on first response, ignoring the possibilty
the sw flow isn't over [as might be the case of the acquisition flow].
As a result, the flow would run unprotected and would cause a double
mutex release [as the additional message completion would release it
while its actually already free].
Change the flow to have a dedicated function to be called at end of each
flow and release the lock.
