gprs-ns: Fix reset state handling

Currently the NS-VC's state is updated from within gprs_ns_tx_reset,
which can lead to an inconsistent state when the RESET_ACK is lost.
In this state, the NSE_S_RESET bit is set but the Tns-reset timer is
not started.

This patch moves the state update into gprs_nsvc_reset. This way, the
state flags are consistent with the timer.

Addresses:
  SGSN -> BSS       NS_ALIVE
  BSS -> SGSN       NS_ALIVE_ACK
  BSS -> SGSN       BVC_RESET
  SGSN -> BSS       NS_STATUS, Cause: NS-VC blocked, NS VCI: 0x65
  and there is no BSS->SGSN NS_ALIVE
