Keisuke Nishimura be7e611274 KVM: arm64: vgic-its: Add error handling in vgic_its_cache_translation 
The return value of xa_store() needs to be checked. This fix adds an
error handling path that resolves the kref inconsistency on failure. As
suggested by Oliver Upton, this function does not return the error code
intentionally because the translation cache is best effort.
