ffmpeg_hw: Don't ignore key parameters when initializing a hw device

Browse Source 
Currently user may use '-init_hw_device type=name' to initialize a hw
device, however the key parameter is ignored when use '-init_hw_device
type=name,key=value'. After applying this patch, user may set key
parameter if needed.
