[Nut-upsdev] newhidups minor bugfix

[Peter Selinger]

I fixed a minor bug in newhidups: some parts of the code confused
iProduct (a string index pointing to a product description string) and
ProductID (a numerical product ID assigned by the manufacturer).  I
deleted the (now unused) iProduct field from the libhid.h:HIDDevice
data structure.  The changes are in CVS, see:

cvs diff -u -r before_PSE_1 -r after_PSE_1
