kernel/kallsyms.c: fix %pB when there's no symbol at the address
__sprint_symbol() should restore original address when kallsyms_lookup()
failed to find a symbol. It's reported when dumpstack shows an address in
a dynamically allocated trampoline for ftrace.
[ 1314.612287] [<ffffffff81700312>] dump_stack+0x45/0x56
[ 1314.612290] [<ffffffff8125f5b0>] ? meminfo_proc_open+0x30/0x30
[ 1314.612293] [<ffffffffa080a494>] kpatch_ftrace_handler+0x14/0xf0 [kpatch]
[ 1314.612306] [<ffffffffa00160c4>] 0xffffffffa00160c3
You can see a difference in the hex address - c4 and c3. Fix it.
