Since the legacy exporting is gone with 2f804aca4832 ("gpiolib: Kill unused GPIOF_EXPORT and Co") there is no need to unexport GPIO on freeing. Remove that call. Note, the other users of this functionality do that explicitly, except one SH boardfile which doesn't free GPIO anyways, so it is safe to drop the call.
