gpiolib: remove redundant callback check 

The presence of the .get_direction() callback is already checked in
gpiochip_get_direction(). Remove the duplicated check which also returns
the wrong error code to user-space.

Fixes: e623c4303e ("gpiolib: sanitize the return value of gpio_chip::get_direction()")
Reported-by: Michael Walle <mwalle@kernel.org>
