target/ppc: Retain hflags_nmsr only for migration
We have eliminated all normal uses of hflags_nmsr. We need
not even compute it except when we want to migrate. Rename
the field to emphasize this.
Remove the fixme comment for migrating access_type. This value
is only ever used with the current executing instruction, and
is never live when the cpu is halted for migration.
