spapr: Provide better error message when slots exceed max allowed 

Currently when user specifies more slots than allowed max of
SPAPR_MAX_RAM_SLOTS (32), we error out like this:

qemu-system-ppc64: unsupported amount of memory slots: 64

Let the user know about the max allowed slots like this:

qemu-system-ppc64: Specified number of memory slots 64 exceeds max supported 32
