Drive-by fix for wtfIfInLock + two violations

wtfIfInLock() method was checking 'this' lock while the code is
actually using mLockDoNoUseDirectly returned by getLockObject(),
thus violation werent reported. This CL changes this and fixes
violations when calling hasIncompatibleAccountsOrNonAdbNoLock.
Also move it to other lock-related methods.
