[PATCH] testsuite: Reset module_do for each ungrouped modules test

[Christophe Lyon]

The ungrouped modules test loop does not reset module_do between
tests.  If a previous test calls unsupported, module_do can remain
set to {"compile" "N"}, causing the CMI checks for subsequent
tests to be skipped.

Reset module_do at the beginning of each iteration, as is already
done for grouped modules tests.
