openpic: fix up loadvm under -M mac99

Issuing loadvm under -M mac99 would fail for two reasons: firstly an incorrect
version number for openpic would cause openpic_load() to abort, and secondly
a cut/paste error when restoring the IVPR and IDR registers caused subsequent
vmstate sections to become misaligned and abort early.
