status: disable deserialize when verbose output requested.

Disable deserialization when verbose output requested.

Verbose mode causes Git to print diffs for modified files.
This requires the index to be loaded to have the currently
staged OID values.  Without loading the index, verbose output
make it look like everything was deleted.
