bfa: comparison with wrong msgtag in bfa_pport_isr()

Compare it with the disable msgtag.

---
Was this maybe intended? otherwise in case BFI_PPORT_I2H_ENABLE_RSP:
the same code is executed. Please review.

+		if (pport->msgtag == i2hmsg.disable_rsp->msgtag)
 			bfa_sm_send_event(pport, BFA_PPORT_SM_FWRSP);
 		break;
 

Making this change alone will break compilation since bfa_pport_disable_rsp_s is not defined. To fix this, we should also replace it with bfa_pport_generic_rsp_s in bfi_pport_i2h_msg_u.

But please keep this as it is for now since I am working on resubmitting 2.1.2.1 patch, and there are a lot of changes in this area.

Thanks
