Harald Welte cc295f6945 firmware/sniffer: Avoid extra call for rbuf_is_full ...

rbuf_write() will tell us in the return value if the buffer was full
(error) or not (success).  Let's use that return value rather than a
theoretically race-y call to rbuf_is_full() before.

It's theoretical as the write happens from IRQ context and the read from
normal process context, so the fill-level cannot really change while
we're in the USART interrupt.  So it doesn't fix a bug, just improves
coding style and also avoids an extra function call + irq-disable/re-enable.
