54b4d1911e media: amphion: delete unnecessary NULL check
vfree(NULL) is safe. NULL check before vfree() is not needed.
Delete them to simplify the code.

d67005b7dc media: amphion: G/S_PARM only for encoder's output queue
G/S_PARM doesn't make sense for the capture queue of a stateful encoder,
unless V4L2_FMT_FLAG_ENC_CAP_FRAME_INTERVAL is set to reserve hardware
resources.

Otherwise it will fail the v4l2-compliance

37ed01d5f2 media: amphion: free ctrl handler if error is set and return error
The typical behavior is to add all controls, then at the end check if
hdl->error was set, and if so, v4l2_ctrl_handler_free is called and
the error is returned.

455e583638 media: amphion: encoder copy timestamp from output to capture
copy the timestamp using the helper function
V4L2_BUF_FLAG_TIMESTAMP_COPY

To implement this, driver will keep the output buffer until it's
encoded, in previous, driver will return the output buffer immediately
after firmware return it
