env: Use better name for variable in env_get_f()
The `nxt` variable actually points to the terminating null-byte of the current env var, and the next env var is at `nxt + 1`, not `nxt`. So a better name for this variable is `end`. Signed-off-by: Marek BehĂșn <marek.behun@nic.cz> Reviewed-by: Simon Glass <sjg@chromium.org>
