Recovery from usage info corruption

Browse Source 
[ Merge of http://go/wvgerrit/46623 ]

If corruption of the usage information file is detected while saving a
streaming license with a PST, usage information file is deleted, so that
a subsequent load keys may succeed.

Also when calling the MediaDrm API releaseAllSecureStops(), an error would
be returned if usage info file was corrupted. Since this file is
deleted successfully, errors have been replaced with warnings.
