HACK: arm64: Fix warning in cpu_enable_uao
Commit a057484ab40f introduced this compiler warning:
arch/arm64/mm/fault.c: In function 'cpu_enable_uao':
arch/arm64/mm/fault.c:690:1: warning: control reaches end of non-void function [-Wreturn-type]
Silence this and make things consistant at runtime by returning zero.
Note, this hack should be both safe and temporary because this function
is being removed from mainline linux [1] as "Since its introduction, the
UAO enable call was broken, and useless."
