Fix potential double close in IMediaMetadataRetriever::setDataSource

IMediaMetadataRetriever::setDataSource(fd, offset, length) takes the ownership
of |fd| on the direct invocation, and doesn't take the ownership on invocation
from Binder. This is inconsintent to other similar methods like
IMediaPlayer::setDataSource, and causes potential double close of |fd|.

This CL changes the caller and implementations to leave the ownership to make
them consistent.
Also, fixes a double close in IMediaPlayerService::setDataSource in an error
case.
