Subject: IB/hfi1: Remove incorrect IS_ERR check
From: Dennis Dalessandro <dennis.dalessandro@xxxxxxxxx>
commit 2b16056f845207967a32497f41cf92b57849f934 upstream.
Remove IS_ERR check from caching code as the function being called does
not actually return error pointers.
Fixes: f19bd643dbde: "IB/hfi1: Prevent NULL pointer deferences in caching code"
