Fix access to uninitialized variable in fill_in_stop_func
This patch changes find_pc_partial_function so that *block is set to
nullptr when it fails, so that fill_in_stop_func won't access an
uninitialized variable.

2019-08-09 Pedro Franco de Carvalho <pedromfc@linux.ibm.com>
* blockframe.c (find_pc_partial_function): Set *block to nullptr
when the function fails.
