Subject:    [PATCH 11/24] IB/qib: clear WAIT_SEND flags when setting QP to error
From:       Mike Marciniszyn <mike.marciniszyn () qlogic ! com>

If these flags are set when the QP is transitioned to the error
state, it will wait until the flags are cleared, which may never
happen if the error transition is due to a link going down.
