gcc 11.4.0, seems to believe this variable may be used uninitialized,
and warns about it (causing a test build failure due to warnings
being treated as errors).
Let's just initialize the variable to 0 to avoid the issue, as the
cost is trivial.
subsys/bluetooth/host/classic/hfp_ag.c: In function
‘bt_hfp_ag_vts_handler’:
1095
subsys/bluetooth/host/classic/hfp_ag.c:3091:17: error: ‘code’ may be
used uninitialized in this function [-Werror=maybe-uninitialized]
1096
3091 | bt_ag->transmit_dtmf_code(ag, code);

The issue can be reproduced for ex. with:
$ mkdir build ; cd build
$ cmake -GNinja -DBOARD=native_sim/native/64 ../tests/bluetooth/shell \
-DCONF_FILE="prj_br.conf"
$ ninja
