i2400m/usb: wrap USB power saving in #ifdef CONFIG_PM
Current code was assuming PM was always enabled, which is not
correct. Code which accesses members in the struct usb_device that are
dependant on CONFIG_PM must be protected the same.
Reported by Randy Dunlap from a build error in the linux-next tree on
07/01/2009.
