ldb_controls: control_to_string avoids crash
Otherwise a malformed control with unexpected NULL data will segfault
ldb_control_to_string(), though this is not very likely to affect
anyone in practice as converting controls to strings is rarely
necessary. If it happens at all in Samba it is in Python code.
Found by Honggfuzz using fuzz_ldb_parse_control.
