The command line switch -A (ignore ASSERTs) has always been available in zdb but was never connected up to the correct global variable. There are times when you need zdb to ignore asserts and keep dumping out whatever information it can get despite the ASSERT(s) failing. It was always intended to be part of zdb but was incomplete. Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Paul Zuchowski <pzuchowski@datto.com> Closes #9610
