[PATCH] staging: greybus: audio: remove redundant slot field

[Pankaj Bharadiya]

gb_audio_manager_module_descriptor's intf_id field maintains the
information about the interface on which module is connected hence
having an extra slot field is redundant.

Thus remove the slot field and its associated code.
