Subject: [PATCH v17 2/8] media: test-drivers: Set REQBUFS minimum number of buffers

Instead of using 'min_queued_buffers' field to specify the
minimum number of buffers to be allocated when calling REQBUF
use 'min_reqbufs_allocation' field which is dedicated to this
purpose.

While at it rename vivid_create_queue() parameter.
