media: uvcvideo: Check for INACTIVE in uvc_ctrl_is_accessible()

Check for inactive controls in uvc_ctrl_is_accessible().

Use the new value for the master_id controls if present, otherwise
use the existing value to determine if it is OK to set the control.
Doing this here avoids attempting to set an inactive control, which
will return an error from the USB device, which returns an invalid
errorcode.

This fixes:
