NS: Factor out gprs_nsvc_start_test() and use it

This function performs  sending a NS-ALIVE PDU and starting Tns-Test,
let's use it in all places where we used to do that.

As part of this, also fix a bug where the sendto() return value (number
of bytes sent) would actually propagate up all the way to
gprs_ns_rx_reset() return value, which in turn affects the test results
on stdout.
