Subject: [PATCH -mm] sysctl: Fix syscall disabled build.

deprecated_sysctl_warning() is used for sys_sysctl(), whether
CONFIG_SYSCTL_SYSCALL is enabled or not. When it was added, it was
added under the CONFIG_SYSCTL section, so it's not defined if we have
the support disabled completely.

  CC      kernel/sysctl.o
kernel/sysctl.c: In function 'sys_sysctl':
kernel/sysctl.c:2601: error: implicit declaration of function 'deprecated_sysctl_warning'
make[1]: *** [kernel/sysctl.o] Error 1
make: *** [kernel] Error 2

This just moves the function past the end of the CONFIG_SYSCTL space
so both configurations are happy.
