staging: pi433: Remove stray gpiod_unexport() call

There is no gpiod_export() and gpiod_unexport() looks pretty much stray.
If user space tools somehow belong to that, they should be fixed, the
gpiod_export() and gpiod_unexport() shouldn't be used in a new code,
GPIO sysfs is deprecated. That said, and taking into account staging
state of the driver, simply drop the stray call.
