Suppress benign warning seen in staleblock.cc

Coverity scan shows this warning in stalelock.cc:373:
    CID 102895:  Null pointer dereferences  (FORWARD_NULL)
    Assigning: "doc.meta" = "NULL".

This shouldn't be a problem, however to suppress this
warning, the entire line of initializing doc.meta to NULL
can be removed as doc is already memset to 0x0.
