[sane-devel] Fix for array subscript error in niash.c

[Johannes Meixner]

Hello,

the newest GNU compiler found an array subscript error
in backend/niash.c of sane-backends-1.0.18, see
https://bugzilla.novell.com/show_bug.cgi?id=246654

It happens because the arrays are defined with a size of optLast
but actually optLast is not the last entry in the enumeration.
Therefore I added an optEndOfList at the very end:
