[PATCH v3 10/13] env: Make return value of env_get_f() behave like sprintf() on success

From: Marek Behún <marek.behun at nic.cz>
Currently the env_get_f() function's return value behaves weirdly: it
returns the number of bytes written into `buf`, but whether this is
excluding the terminating NULL-byte or including it depends on whether
there was enough space in `buf`.
Change the function to always return the actual length of the value of
the environment variable (excluding the terminating NULL-byte) on
success. This makes it behave like sprintf().
All users of this function in U-Boot are compatible with this change.
