ib_srpt: always set response for task management
The SRP specification requires:
"Response data shall be provided in any SRP_RSP response that is sent in
response to an SRP_TSK_MGMT request (see 6.7). The information in the
RSP_CODE field (see table 24) shall indicate the completion status of
the task management function."
So fix this to avoid the SRP initiator interprets task management functions
that succeeded as failed.
