IB/usnic: delete unneeded IS_ERR test

Browse source 
kzalloc doesn't return ERR_PTR, so there is no need to test for it.

The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@@
expression x,e;
@@

* x = kzalloc(...)
... when != x = e
* IS_ERR_OR_NULL(x)
// </smpl>
