gbprox_rx_ptp_from_bss: fix dangling pointer

Building with gcc (Debian 12.2.0-14) 12.2.0 and --enable-werror fails
without this during "make distcheck":

../../../src/gb_proxy.c:450:24: error: storing the address of local variable 'tp' in '((struct libgb_msgb_cb *)msg)[2].bssgp_cell_id' [-Werror=dangling-pointer=]
  450 |         msgb_bcid(msg) = (void *)&tp;

This means that gcc now warns (and we turn that into an error) if one
assigns the address of a local (stack) variable to something allocated
on the heap, and doesn't remove that reference before ending the function
(invalidating the stack).
