Subject: [PATCH] init: mark envp_init as static

Sparse reports a warning that 'envp_init' has no prior
declaration:

  warning: symbol 'envp_init' was not declared. Should it be static?

The variable is only used within init/main.c and does not
need external linkage. Mark it as static to limit its scope
and fix the sparse warning.
