mds: rejournal using EUpdate instead of EOpen if no caps in check_inode_max_size

Using EOpen on non-open files is imprecise.  More importantly, if
it is a snapped inode, the EOpen replay code won't be able to
look up the ino and will throw an assertion.

So, use EUpdate instead to record the new info when necessary.
