IB/mthca: Fix RESET to ERROR transition

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.
