IB/mthca: Fix RESET to ERROR transition

Browse source

According to the IB spec, a QP can be moved from RESET to the ERROR 
state, but mthca firmware does not support this and returns an error if 
we try.  Work around this FW limitation by moving the QP from RESET to
INIT with dummy parameters and then transitioning from INIT to ERROR.
