Fix fd leak while bypassing transcoding in media APIs
To call the media service while bypassing transcoding there are 4 file
descriptors involved:
A: The original file descriptor the app owns and is responsible for
closing
B: Dupe of A, to pass into the MediaStore API as an input to receive a
non-transoding fd
C: The output from the MediaStore API
D: Final fd owned by the media service, after C gets duped over binder
as part of setDataSource
We were leaking (B) and (C). Now we close them appropriately.
