libavutil: hwcontext_amf: remove unreachable statements

Browse Source 
Inside the amf_device_derive() function, there seem to be some
unreachable 'break' statements, which can be removed.
And also the final 'return 0' statement will also be unreachable
especially since there is a default case in the switch block.
