[PATCH 2/4] gpio: virtuser: fix handling of multiple conn_ids in lookup table

[Koichiro Den <koichiro.den@xxxxxxxxxxxxx>]

Creating a virtuser device via configfs with multiple conn_ids fails due
to incorrect indexing of lookup entries. Correct the indexing logic to
ensure proper functionality when multiple gpio_virtuser_lookup are
created.
