Bad malloc in player_start_decoding_threads

[martri]

Hello,

The malloc for DecoderData at `player_start_decoding_threads' is being passed size-of-pointer and not size-of-struct.

I was getting random SIGSEGVs due to DecoderData being corrupt (I build with ndk r10e and run on Android 5.1); once applying the fix it seems to work fine.

Thank you and kind regards,
Marco.
