Add support for List-Directed IPL (LD-IPL) type pointers.
We check for a boot record indicating LD-IPL and use it if it is valid,
otherwise we use the CCW CDL or LDL format as usual. When a block is accessed
during IPL the block number is first calculated based on the cylinder,

On a panic during IPL (i.e. a device failed to boot) check for another device

This is a small fix to the IPL behavior in case the user has entered an invalid
loadparm. The loadparm is a very specific value, which must be deliberately set
by the user. Therefore, if it is not valid, then it is a mistake in the guest
configuration.
As such, we immediately
