[PATCH] bootm: Fix flags used for bootargs string substitution

[Piotr Kubik]

Commit <51bb33846ad2> introduced a feature of bootargs
string substitution and changed a flag used in
bootm_process_cmdline_env() call to be either true or false.
With this flag value, condition in bootm_process_cmdline()
`if (flags & BOOTM_CL_SUBST)` is never true
and process_subst() is never called.
