leveldb Team 068d5ee1a3 leveldb: Check slice length in Footer::DecodeFrom() ...

Without this check decoding the footer in Table::Open() can read
uninitialized bytes from a buffer allocated on the stack if the file
was unexpectedly short.

In practice this is probably fine since this function validates a magic
number but MSan complains about branching on uninitialized data.
