Fix static analyzer warnings
It was unhappy about uninitialized values potentially being passed into
calls. The warnings were:
frameworks/av/media/libstagefright/DataSource.cpp:254:22: warning:
Function call argument is an uninitialized value
frameworks/av/media/libstagefright/MPEG4Extractor.cpp:4528:17: warning:
Function call argument is an uninitialized value
(The latter was complaining about both `size` and `offset`)
Bug: None
Test: Still builds; static analyzer is now less unhappy.
