util: initialise CCriticalSection's diagnostic fields at construction

pszFile/nLine were first written by CRITICAL_BLOCK on entry, so an
instance embedded in a dynamically allocated object (CNode::cs_vSend,
cs_vRecv, cs_inventory) held indeterminate values until its first
lock -- anything reading them for diagnostics dereferenced a wild
pointer.
