cpu/x86/smm/smm_module_loader.c: Avoid static analysis error "unused value"
In procedure smm_load_module, variables fxsave_size and fxsave_area are set
to 0 and NULL, but if CONFIG_SSE is enabled, they are overwritten. Change
the code setting the value to an "else" of the "if" testing CONFIG_SSE, thus
avoiding static analysis error.
BUG=b:112253891
TEST=Build and boot grunt.
