KUDU-2433. Don't try to symbolize a nullptr
Don't try to symbolize a nullptr when walking the stack. It may be
possible to get a null pc in the case of unwinding through a stack frame
in a library that wasn't built with frame pointers, or if the stack was
corrupted.
Attempting to symbolize a nullptr with this code path will overflow the
null pointer from 0 to UINT64_MAX, which causes a fatal exception in
UBSAN builds.
