[sane-devel] fixes for regressions in epjitsu v26 backend

[Peter Marschall]

Hi,

epjitsu backend v26 contains a regression for ADF scanners:
It makes setting the width setting useless.

The three attached patches contain the minimal changes to revert this "mis-
feature".

Please apply them to sane-backends' master branch to make the life of epjitsu 
ADF scanner owners as easy as it was before v26.

If you prefer getting them from a git repository, you can find them at
  https://github.com/marschap/sane-backends/tree/epjitsu-regression-fixes

Thanks in advance
Peter
