[PATCH 5/5] drivers/char/applicom.c: ac_ioctl should not always returns 0

[Lifeng Sun <lifongsun@gmail.com>]

It should return error code properly instead of always returning 0.

This driver does not seem to be actively maintained from my brief
investigation. Apologies to the maintainers that I have missed.
