v4l2: fix debug category initialisation again

Browse source 
Would spew warnings on the rpi4 when calling into
gst_v4l2_object_get_codec_caps() from the probe_and_register()
function since the v4l2_debug category initialisation would
only be done later as part of the element/device provider
registration.

Also log things in the probe function to the v4l2 category
instead of the default category while we're at it.
