Fix crash on parsing some inf files

ndiscvt uses 16 entry array for words into which it parses
comma-separated lists of strings, like AddReg line in

[somesection]
AddReg = foo.reg, bar.reg, baz.reg, quiz.reg

Overflows were not checked so it crashed on a line with 17 words
encountered in some Broadcom/Dell Wireless 1704 802.11b-g-n driver

So extend the array up to 32 entries and add an overflow check.
