Subject[PATCH] static_call: fix unused variable warning
From
'mod' is not used when !CONFIG_MODULES. Mark as __maybe_unused to
fix the following warning:

kernel/static_call.c: In function ‘__static_call_update’:
kernel/static_call.c:153:18: warning: unused variable ‘mod’ [-Wunused-variable]
153 | struct module *mod = site_mod->mod;
| ^~~
