[PATCH v3 05/13] env: Inline env_get_char() into its only user

[Simon Glass]

From: Marek Behún <marek.behun at nic.cz>

This function is a relic from the past when environment was read from
underlying device one character at a time.

It is used only in the case when getting an environemnt variable prior
relocation, and the function is simple enough to be inlined there.

Since env_get_char() is being changed to simple access to an array, we
can drop the failing cases and simplify the code (this could have been
done before, since env_get_char() did not fail even before).
