sysfs: fix for thinko with sysfs_bin_attr_init()
After merging the final tree, today's linux-next build (powerpc allyesconfig) failed like this: drivers/pci/pci-sysfs.c: In function 'pci_create_legacy_files': drivers/pci/pci-sysfs.c:645: error: lvalue required as unary '&' operand drivers/pci/pci-sysfs.c:658: error: lvalue required as unary '&' operand Caused by commit "sysfs: Use sysfs_attr_init and sysfs_bin_attr_init on dynamic attributes" interacting with commit "sysfs: Use one lockdep class per sysfs attribute") both from the driver-core tree.
