google/parrot/smihandler.c: Use `battery_critical_logged` only with `ELOG_GSMI`

Removing `-Wno-unused-but-set-variable` from `CFLAGS` results in the
    following error.

CC         mainboard/google/parrot/smihandler.smm.o
    	src/mainboard/google/parrot/smihandler.c: In function 'mainboard_smi_ec':
    	src/mainboard/google/parrot/smihandler.c:97:13: error: variable 'battery_critical_logged' set but not used [-Werror=unused-but-set-variable]
    	cc1: all warnings being treated as errors

As the variable is only used, when the Kconfig variable `ELOG_GSMI` is
    not zero, only declare and set it in that case.
