arm64: Use consistent naming for errata handling

This is a cosmetic change to rename the functions dealing with
the errata work arounds to be more consistent with their naming.

1) check_local_cpu_errata() => update_cpu_errata_workarounds()
check_local_cpu_errata() actually updates the system's errata work
arounds. So rename it to reflect the same.

2) verify_local_cpu_errata() => verify_local_cpu_errata_workarounds()
Use errata_workarounds instead of _errata.
