sysfs: build fix

x86.git testing found the following build failure on v2.6.26-rc1:

  In file included from include/linux/kobject.h:22,
                   from include/linux/module.h:17,
                   from include/linux/crypto.h:22,
                   from arch/x86/kernel/asm-offsets_32.c:8,
                   from arch/x86/kernel/asm-offsets.c:3:
  include/linux/sysfs.h:201: error: redefinition of 'sysfs_update_group'
  include/linux/sysfs.h:195: error: previous definition of 'sysfs_update_group' was here
  make[1]: *** [arch/x86/kernel/asm-offsets.s] Error 1
  make: *** [prepare0] Error 2

with the following config:

    http://redhat.com/~mingo/misc/config-Sun_May__4_07_09_30_CEST_2008.bad

the reason for the build failure is the duplicate definition of the
sysfs_update_group() inline function in include/linux/sysfs.h.

The duplication was a merge error: it was added via -mm by commit
v2.6.25-7262-g2850699, "sysfs: sysfs_update_group stub for
CONFIG_SYSFS=n" a day before v2.6.26-rc1, but a day before that the same
commit was already merged upstream via the sysfs tree, with commit
v2.6.25-7211-g1cbfb7a.
