gb_proxy: Ensure cell info is up to date when receiving PTP-BVC reset

When a BSS resets its BVC and reuses a BVCI with a differente cell id
the SGSN BVC still has the old cell information.

This results in the SGSN receiving a BVC reset for the old cell which in
turn leads to all sorts of issues (probably also with paging) and
conflicting information since the cell info is also present in the
UL-UNITDATA and this is just passed through from the BSS.

Instead of reusing the old BVC on the SGSN side free any existing and create
new ones.
