media: rcar-vin: Drop min_queued_buffers
The R-Car VIN driver already uses a scratch buffer to sustain capture
operations in absence of a frame buffer provided by userspace.
There is no reason to require 4 buffers queued at all times for the
driver to operate. Drop min_queued_buffers from the VIN driver to allow
single-frame capture operations.
