Before using the result of env_get("stdin") we must check if it is NULL.
Avoid #if. This resolves the -Wunused-but-set-variable issue and we don't
need a dummy assignment in the else branch. Anyway this warning is
disabled in the Makefile.
For sake of readability use an early return after the configuration check.
Checking CONFIG_SPL_BUILD is incorrect as env_get() is only defined if
CONFIG_$(SPL_TPL)ENV_SUPPORT=y.
Fixes: 985ca3945f
("spl: input: Allow input in SPL and TPL")
