[PATCH 1/4] gpio: virtuser: fix missing lookup table cleanup on probe failure

[Koichiro Den]

When a virtuser device is created via configfs and the probe fails due
to an incorrect lookup table, the table is not removed. This prevents
subsequent probe attempts from succeeding, even if the issue is
corrected, unless the device is released.

Ensure the lookup table is removed whenever the probe fails.
