[PATCH 1/2]drivers/usb/core/sysfs.c Fix variable 'retval' set but not used

["Justin P. Mattock" <justinmattock@gmail.com>]

The below fixes a warning generated by GCC:
  CC      drivers/usb/core/sysfs.o
drivers/usb/core/sysfs.c: In function 'usb_create_sysfs_intf_files':
drivers/usb/core/sysfs.c:889:6: warning: variable 'retval' set but not used

Let me know if these are totally wrong etc.. And I'll try
my best to resend properly..
