Do not call RecoverySystem with DPMS lock held

Note DPM.wipeData() on a secondary user is now blocking, just like
it's been always blocking on the primary user.

Test: Manually tested wipeData() with ApiDemos, both on 1) the primary user,
2) a secondary user and 3) work profile.

Test: adb shell am instrument -e class com.android.server.devicepolicy.DevicePolicyManagerTest -w com.android.frameworks.servicestests
