Fix missing P4Runtime groups because of infinite delete/insert cycle

The fix is simple: when cleaning up inconsistent entries from device,
we update the mirror when the response is received, and not before
sending the request. Otherwise, if delete goes wrong, writes happening
right after reconciliation cycle might find an inconsistent mirror state.

When writing entries (e.g. apply group/flow rule) we keep updating the
mirror before sending the request to handled the case of back-to-back
writes.
