gpio: fix getting nonexclusive gpiods from DT

Browse Source 
Since commit ec757001c8 ("gpio: Enable nonexclusive gpiods from DT
nodes") we are able to get GPIOD_FLAGS_BIT_NONEXCLUSIVE marked gpios.
Currently the gpiolib uses the wrong flags variable for the check. We
need to check the gpiod_flags instead of the of_gpio_flags else we
return -EBUSY for GPIOD_FLAGS_BIT_NONEXCLUSIVE marked and requested
gpiod's.
