gbproxy: Send STATUS(BVCI unknown) to BSS on unknown PTP BVCI 

Currently BSSGP PTP messages are silently dropped when the BVCI is
not known and patching is enabled. The nanoBTS will not recognize
this and continue to send messages on the BVCI. If it receives a
STATUS(BVCI unknown) instead, it will start a BVC reset procedure
instead.

This patch modifies gbprox_rx_ptp_from_bss() to return a
STATUS(BVCI unknown) to the BSS instead of dropping the message.
