[PATCH 3/3] fix setattr error handling in sysfs, configfs

[Greg Kroah-Hartman]

From: Nick Piggin <npiggin@suse.de>

sysfs and configfs setattr functions have error cases after the generic inode's
attributes have been changed. Fix consistency by changing the generic inode
attributes only when it is guaranteed to succeed.
