Commit fce886a60207 ("KVM: arm64: Plumb the pKVM MMU in KVM") made the initialization of the local memcache variable in user_mem_abort() conditional, leaving a codepath where it is used uninitialized via kvm_pgtable_stage2_map().

This can fail on any path that requires a stage-2 allocation without transition via a permission fault or dirty logging.

Applied to fixes, thanks!
