bts: bts_tfi_find_free(): fix -Wmaybe-uninitialized (false positive)
We cannot see how uninitialized access is possible, but gcc v13.2.1
does complain about it. Let's work this around by assigning an
invalid value, like trx_count_free_tfi() does.
src/bts.cpp: In function 'int bts_tfi_find_free(const gprs_rlcmac_bts*,
gprs_rlcmac_tbf_direction,
uint8_t*, int8_t)':
warning: 'tmp_first_tfi' may be used uninitialized [-Wmaybe-uninitialized]

Fixes: OS#6190
