[SCSI] bnx2i: Added return code check for chip kwqe submission request

Added the handling for cases when a chip request is made to the
CNIC module but the hardware is not ready to accept.  This would
lead to many unnecessary wait timeouts.
This code adds check in the connect establishment and destruction
path.
