KVM: arm64: Unify UNDEF injection helpers
We currently have two helpers (undef_access() and trap_undef()) that
do exactly the same thing: inject an UNDEF and return 'false' (as an
indication that PC should not be incremented).
We definitely could do with one less. Given that undef_access() is
used 80ish times, while trap_undef() is only used 30 times, the
latter loses the battle and is immediately sacrificed.
We also have a large number of instances where undef_access() is
open-coded. Let's also convert those.
