[PATCH] staging: (sb105x) Fix compile error seen if PARPORT_PC is undefined

[Guenter Roeck <linux@roeck-us.net>]

Fix:
ERROR: "parport_pc_probe_port" [drivers/staging/sb105x/sb105x.ko] undefined!

by making the code calling it conditional. Also remove the external reference to
parport_pc_probe_port() from the sb105x source file, as it doesn't belong there.
