pinctrl: qcom: ssbi: convert null test to IS_ERR test

Since commit 323de9efdf3e ("pinctrl: make pinctrl_register() return proper
error code"), pinctrl_register returns an error code rather than NULL on
failure.  Update some drivers that were introduced more recently.

The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>

expression e,e1,e2;
@@

e = pinctrl_register(...)
... when != e = e1
if (
-   e == NULL
+   IS_ERR(e)
   ) {
     ...
     return
-      e2
+      PTR_ERR(e)
     ;
     }
// </smpl>
