[PATCH v6] ppc: well form kvmppc_hint_smt_possible error hint helper

[Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com>]

Make kvmppc_hint_smt_possible hint append helper well formed:
rename errp to errp_in, as it is IN-parameter here (which is unusual
for errp), rename function to be kvmppc_error_append_*_hint.
