Zhang Wensheng 4311ad1e76 nbd: fix possible overflow on 'first_minor' in nbd_dev_add() 
commit 858f1bf65d3d9c00b5e2d8ca87dc79ed88267c98 upstream.

When 'index' is a big numbers, it may become negative which forced
to 'int'. then 'index << part_shift' might overflow to a positive
value that is not greater than '0xfffff', then sysfs might complains
about duplicate creation. Because of this, move the 'index' judgment
to the front will fix it and be better.
