cxlflash: Fix host link up event handling
Following a link up event, the LUNs available to the host may
have changed. Without rescanning the host, the LUN topology is
unknown to the user. In such a state, the user would be unable
to locate provisioned resources.
To remedy, the host should be rescanned after a link up event.
