static_call: Fix unused variable warn w/o MODULE
Here is the warning converted as error and reported by GCC: kernel/static_call.c: In function ‘__static_call_update’: kernel/static_call.c:153:18: error: unused variable ‘mod’ [-Werror=unused-variable] 153 | struct module *mod = site_mod->mod; | ^~~ cc1: all warnings being treated as errors make[1]: *** [scripts/Makefile.build:271: kernel/static_call.o] Error 1 This is simply because since recently, we no longer use 'mod' variable elsewhere if MODULE is unset. When using 'make tinyconfig' to generate the default kconfig, MODULE is unset. There are different ways to fix this warning. Here I tried to minimised the number of modified lines and not add more #ifdef. We could also move the declaration of the 'mod' variable inside the if-statement or directly use site_mod->mod.
