From: Sebastian Ott <sebott@redhat.com>

Invariant system id registers are populated with host values
at initialization time using their .reset function cb.

These are currently called get_* which is usually used by
the functions implementing the .get_user callback.

Change their function names to reset_* to reflect what they
are used for.
