why not while (err_code & CMDSTATUS_ACTIVE_MASK) ?
the cmdstatus reg may change in load to err_code and while judge,
so suggest always use err_code.

1. the err_code come from idxd->u.pci->regs->cmdstatus which may >0, I think
it better use negative explicit.
2. suggest use goto err which also free pci memory.

need free idxd.u.pci's memory.

The name should be 'snprintf(qname, sizeof(qname), "%s-q%d", name, qid)', and also
free auxiliary memory like idxd.u.pci
