dtc: Fix summary calculation in testsuite

[David Gibson <david@gibson.dropbear.id.au>]

The bookkeeping for producing the testsuite summary (total number of
tests passed, failed and so forth) is broken.  It uses $? across
several tests, but for checks after the first, the value of $? will no
longer contain the original return code, but just that from the
previous test.  This patch fixes the problem.
