[PATCH 2/7] open_by_handle: verify dir content only with -r flag

[Amir Goldstein <amir73il@gmail.com>]

Without -r flag file handles are opened, but file content is not read.
Treat dir file hanldes, similarly. without -r flag, open dir file
handle, but don't verify its content.

This is going to be used by tests for which dir content is changed
between encode and decode of dir file handle.
