sched: compilation fix with gcc 3.4.6

I found that 2.6.27-rc5-mm1 does not compile with gcc 3.4.6.
The error is:
  CC      kernel/sched.o
kernel/sched.c: In function `start_rt_bandwidth':
kernel/sched.c:208: sorry, unimplemented: inlining failed in call to 'rt_bandwidth_enabled': function body not available
kernel/sched.c:214: sorry, unimplemented: called from here
make[1]: *** [kernel/sched.o] Error 1
make: *** [kernel] Error 2

It seems that the gcc 3.4.6 requires full inline definition before first usage.
The patch below fixes the compilation problem.
