A fresh look after work made the resampler initialization code pop out.

The problem is in the sink connection being made from
"module-rtp-recv.c", the "PA_SINK_INPUT_VARIABLE_RATE" flag should be
passed into "pa_sink_input_new", but is not there.  Made the change and
tested it, fixes the problem.  Checked and head-of- tree off of the
pulseaudio.org source browsing link does not have this fix either.

One-liner patch attached.
