[PATCH] scx200_acb: Fix return on init error

The scx200_acb driver shouldn't return failure after initialization
if it successfully registered at least one i2c_adapter, else we are
leaking resources. The driver was OK in that respect up to 2.6.16, a
recent change broke it.

This is part of the fix to bug #6445.
