scsi: qla2xxx: Set NVMe status code for failed NVMe FCP request

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 transferred 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, use NVME_SC_INTERNAL to indicate an
error which aligns it with the lpfc driver.
