uml: handle block device hotplug errors

If a disk fails to open, i.e.  its host file doesn't exist, it won't be
removable because the hot-unplug code checks the existence of its gendisk.
This won't exist because it is only allocated for successfully opened disks.
Thus, a typo on the command line can result in a unusable and unfixable disk.

This is fixed by freeing the gendisk if it's there, but not letting that
affect the removal.
