pc-dimm: fix crash when invalid slot number is used
QEMU will crash with:
Segmentation fault (core dumped)
when negative slot number is used, ex:
qemu-system-x86_64 -m 1G,maxmem=20G,slots=256 \
-object memory-backend-ram,id=mem1,size=1G \
-device pc-dimm,id=dimm1,memdev=mem1,slot=-2
fix it by checking that slot number is within valid range.
