Subject: [PATCH] Updated: always show the keyguard on device lockdown
Additionally, don't hide keyguard when it's disabled if the user has locked
down the device.
Manual test steps:
1. Enable app pinning and disable "Ask for PIN before unpinning" setting
2. Pin an app (ie: Settings)
3. Lockdown from the power menu
4. Observe: user is brought to the keyguard, primary auth is
required to enter the device.
=> After entering correct credential, the device is still in
app pinning mode.
=> After entering an incorrect credential, the keyguard remains
showing and the user can attempt again up to the limit
