[PATCH] sisusbvga: Fix oops on disconnect.

[Will Newton]

Remove the message printed with dev_info on disconnect after sisusb_dev has
potentially been zeroed by sisusb_delete. The message does not provide
any extra information over that which the USB subsystem prints as standard
so just kill it.

[PATCH] sisusbvga: Fix oops on disconnect.

From: Will Newton <will.newton@gmail.com>

Remove dev_info call on disconnect. The sisusb_dev pointer may have been
set to zero by sisusb_delete at this point causing an oops.

The message does not provide any extra information over the standard USB
subsystem output so removing it does not affect functionality.
