Please add 17gpu+ mining support
Ccminer works well with 16 gpu system
But when adding 17's card, card identified incorrectly.

Here is what we have with ccminer -n on the system with 17 gpu's

c:\miner\Desktop\ccminer-x86-2.2.4-cuda9>ccminer -n
*** ccminer 2.2.4 for nVidia GPUs by tpruvot@github ***
    Built with VC++ 2013 and nVidia CUDA SDK 9.0 32-bits

  Originally based on Christian Buchner and Christian H. project
  Include some kernels from alexis78, djm34, djEzo, tsiv and krnlx.
