Fixed VM memory leak in AudioSystem JNI interface

The function android_media_AudioSystem_error_callback from AudioSystem
JNI interface is using FindClass function but does not delete the
reference created by VM in this function.
By doing this call, VM will add a local reference in IndirectRefTable
and it's the caller's job to delete this reference.
By not doing this, everytime this callback is called, a new reference is
added and never deleted.
The effect is crashing the VM running system_server:

E/dalvikvm( 3071): JNI ERROR (app bug): local reference table overflow (max=512)
W/dalvikvm( 3071): JNI local reference table (0x732da288) dump:

In this case, PID 3071 is system server.

Fixing parcel leaks to avoid virtual memory leak

Client has to call recycle() on parcel object after its usage
otherwise native layer of binder won't clear the resources of
