[2.6 patch] atalk compile errors with SYSCTL=n

[Adrian Bunk <bunk@xxxxxxxxx>]

I'm getting the following compile error in 2.6.8-rc4-mm1 (but it 
doesn't seem to be specific to -mm) with CONFIG_SYSCTL=n:

<--  snip  -->

...
  LD      .tmp_vmlinux1
net/built-in.o(.init.text+0x74db): In function `atalk_init':
: undefined reference to `atalk_register_sysctl'
make: *** [.tmp_vmlinux1] Error 1

<--  snip  -->


The following patch fixes this issue:
