Alex Dale 3142782e06 Added mutex for reserved_license_ids_.
[ Merge of http://go/wvgerrit/150849 ]
[ Cherry-pick of http://ag/17919183 ]

DeviceFiles uses a static variable for tracking license IDs which
have been reserved by a CDM session before officially storing the
license on the device.  This variable was not protected by a mutex,
and a rare race condition would arise, either crashing the service
or getting it stuck in a loop.

This CL adds a mutex for protecting the set of reserved IDs.
