gpio: max730x: eliminate double free
The function __max730x_remove is called from the remove functions of
drivers/gpio/gpio-max7300.c and drivers/gpio/gpio-max7301.c. In both
cases, the probe function allocates ts using devm_kzalloc. Explicitly
freeing such a value with kfree will cause a double free.
