[PATCH 3/5] media: mtk-vcodec: change the venc handler funcs to return int

[Dafna Hirschfeld]

Currently the functions handle_enc_init_msg, handle_enc_encode_msg
return void and set vpu->failure to 1 in case of failure.
Instead, change the functions to return non 0 in case of failure
and then the vpu->failure is updated to their return value.
