[ofa-general] [PATCH] IB/core - reset to error state transition not allowed

[Ralph Campbell]

I was reviewing the QP state transition diagram in the IB 1.2.1
spec. and the code for qp_state_table[], and noticed that
the code allows a QP to be modified from IB_QPS_RESET to
IB_QPS_ERR whereas the notes for figure 124 (pg 457)
specifically says that this transition isn't allowed.
