[WINLOGON] Correctly reset LogonState in case logon or shutdown fails (#8133)

Reset `LogonState` back to `STATE_LOGGED_OFF` before invoking
`WlxDisplaySASNotice()` when:
- in `STATE_LOGGED_OFF_SAS` state, `HandleLogon()` failed;
- or when an attempted shutdown operation failed.

This fixes the resulting inconsistent `LogonState` that happened if
any of these operations failed due to legitimate reasons. For example,
a corrupted user profile that caused the login attempt to abort, or,
an ongoing shutdown attempt being aborted as well.

One of the user-visible effects of this inconsistency, was the inability
to access the familiar Logged-Out SAS dialog by pressing Ctrl-Alt-Del at
the invite (SAS notice) dialog, because the `LogonState` was incorrectly
left into the `STATE_LOGGED_OFF_SAS` state, instead of being reset to
`STATE_LOGGED_OFF`.

----

Typical scenario:
The "Administrator" user, who is auto-logged-in by default after the
installation, gets a corrupted ntuser.dat profile registry hive if the
2nd-stage installation is aborted at the end by force-restarting ReactOS.
After reboot, ReactOS tries to log into the account, but fails, and goes
back to the Ctrl-Alt-Del invite dialog.
Before this fix, the user couldn't go into the Logged-Out SAS dialog to
enter new login credentials and attempt login to another account.
This is now fixed.
