drivers/net/wan/dscc4.c: fix error return code
Move up the initialization of rc so that failure of pci_alloc_consistent
returns -ENOMEM as well.
A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
@@
identifier ret;
expression e1,e2;
@@
if (ret < 0)
{ ... return ret; }
... when != ret = e1
when forall
*if(...)
{
... when != ret = e2
* return ret;
}
// </smpl>
