Building nvramcui with i386-elf-gcc (coreboot toolchain
v2021-04-06_7014f8258e) 8.3.0 and Link Time Optimization (LTO) enabled
in libpayload (`CONFIG_LP_LTO=y`) fails with the error below.
LPGCC nvramcui.bin

`pair_content()` returns in case `PAIR_NUMBER(attr)` is invalid, so
guard the usage of `serial_set_color()`.
if (pair < 0 || pair >= COLOR_PAIRS || !fg || !bg)
return ERR;
Note, building with x86_64-linux-gnu-gcc-10 (Debian 10.2.1-6) 10.2.1
20210110 does *not* fail.
