[Spice-devel] [PATCH 3.7/12 v2] __new_channel -> red_worker_new_channel()

From: Marc-André Lureau <marcandre.lureau at gmail.com>

Rename and lightly refactor the function that creates new common
channels for RedWorker (essentially Cursor and Display channels).

Signed-off-by: Jonathon Jongsma <jjongsma at redhat.com>

Changes since v1:
 - rename variable from 'cursor' to 'cursor_channel'
