media: vivid: add vivid_create_queue() helper

Refactor some of the vivid_create_instance code by using a
new vivid_create_queue() helper function.

Also add some sanity checks for the node_types vs input/output_types
module options.

This patch resolves these two smatch parse errors:

drivers/media/platform/vivid/vivid-core.c:1679 vivid_create_instance() parse error: OOM: 3002600Kb sm_state_count = 6160113
drivers/media/platform/vivid/vivid-core.c: drivers/media/platform/vivid/vivid-core.c:1679
vivid_create_instance() parse error: __split_smt: function too hairy.  Giving up after 33 seconds
