nios2: mm: do not invoke OOM killer on kernel fault OOM

Browse Source 
Follow commit 871341023c771ad.

Kernel faults are expected to handle OOM conditions gracefully (gup,
uaccess etc.), so they should never invoke the OOM killer.  Reserve
this for faults triggered in user context when it is the only option.
