[PATCH -next] powerpc/security: Make symbol 'stf_barrier' static

[Li Huafei]

The sparse tool complains as follows:

arch/powerpc/kernel/security.c:253:6: warning:
 symbol 'stf_barrier' was not declared. Should it be static?

This symbol is not used outside of security.c, so this commit marks it
static.
