In order to invalidate a single palette cache item, we were using
spice_marshall_msg_cursor_inval_one(), which is the marshal function
used to send an invalidation message for the Cursor channel's cache.
This didn't cause any problems because SPICE_MSG_CURSOR_INVAL_ONE and
SPICE_MSG_DISPLAY_INVAL_PALETTE have the same message ID and parameters,
but it's better to use the correct marshalling function.

Changes since last version:
- leave the PIPE_ITEM_TYPE_INVAL_ONE case in
display_channel_client_release_item_before_push().
without that change, it introduces this regression:
