KVM: guest_memfd: Drop a superfluous local var in kvm_gmem_fault_user_mapping()
Drop the local "int err" that's buried in the middle guest_memfd's user
fault handler to avoid the potential for variable shadowing, e.g. if an
"err" variable were also declared at function scope.
No functional change intended.
