Subject: [PATCH 10/21] powerpc: Add missing prototype for slb_miss_bad_addr

In commit f0f558b131db ("powerpc/mm: Preserve CFAR value on SLB miss caused
by access to bogus address"), the function slb_miss_bad_addr was added
without a prototype. This commit adds it.

Fix a warning (treated as error in W=1):

  CC      arch/powerpc/kernel/traps.o
arch/powerpc/kernel/traps.c:1498:6: error: no previous prototype for ‘slb_miss_bad_addr’ [-Werror=missing-prototypes]
 void slb_miss_bad_addr(struct pt_regs *regs)
      ^~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors
