powerpc/ptrace: Fix brk.len used uninitialised
With some CONFIGS it's possible that in ppc_set_hwdebug, brk.len is
uninitialised before being used. It has been reported that GCC 4.2 will
produce the following error in this case:
arch/powerpc/kernel/ptrace.c:1479: warning: 'brk.len' is used uninitialized in this function
arch/powerpc/kernel/ptrace.c:1381: note: 'brk.len' was declared here
This patch corrects this.
