HIDL: unsilence error for local Java binder

Browse Source 
HIDL Java never originally supported passthrough HALs. However, even
though after a series of bug fixes were created, they are believed to
work, they are still untested, and there is a desire to avoid adding
additional complexity by introducing this usecase, which hasn't been
needed from the birth to the beginning of the deprecation of HIDL.

Bug: 169369810
Test: RemoteException, instead of silent failure
