IB/mlx4: Fix error path in create_qp_common()

The error handling code at err_wrid in create_qp_common() does not
handle a userspace QP attached to an SRQ correctly, since it ends up
in the else clause of the if statement.  This means it tries to
kfree() the uninitialized qp->sq.wrid and qp->rq.wrid pointers.  Fix
this so we only free the wrid arrays for kernel QPs.
