Igor Mammedov 22235bb609 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.
