IB/srp: Don't wait for response when QP is in error state.
When there is a call to send_tsk_mgmt SRP posts a send and waits for 5
seconds to get a response.
When the QP is in the error state it is obvious that there will be no
response so it is quite useless to wait. In fact, the timeout causes
SRP to wait a long time to reconnect when a QP error occurs. (Each
abort and each reset_device calls send_tsk_mgmt, which waits for the
timeout). The following patch solves this problem by identifying the
failure and returning an immediate error code.
