The qla2xxx driver knows when request was processed successfully or not. But it always sets the NVME status code to 0/NVME_SC_SUCCESS. The upper layer needs to figure out from the rcv_rsplen and transferred_length variables if the request was successfully. This is not always possible, e.g. when the request data length is 0, the transferred_length is also set 0 which is interpreted as success in nvme_fc_fcpio_done(). Let's inform the upper layer (nvme_fc_fcpio_done()) when something went wrong.nvme_fc_fcpio_done() maps all non NVME_SC_SUCCESS status codes to NVME_SC_HOST_PATH_ERROR. There isn't any benefit to map the QLA status code to the NVME status code. Therefore, let's use NVME_SC_INTERNAL to indicate an error which aligns it with the lpfc driver.
