[sane-devel] Fix for array subscript error in sanei_ab306.c

[Johannes Meixner]

Hello,

the newest GNU compiler found an array subscript error
in sanei/sanei_ab306.c of sane-backends-1.0.18, see
https://bugzilla.novell.com/show_bug.cgi?id=239953

It happens if the value of "base" is none of the listed values
in the "port" array because in this case i == 8 from the "for"
statement above.

This is a fix:
