On linux the list debug code has been setting off a failure when checking that the node->next->prev value is pointing back at the node. At times this check evaluates to 0xdead. When removing a child from a gang ABD we must acquire the child's abd_mtx to make sure that the same ABD is not being added to another gang ABD while it is being removed from a gang ABD. This fixes a race condition when checking if an ABDs link is already active and part of another gang ABD before adding it to a gang. Added additional debug code for the gang ABD in abd_verify() to make sure each child ABD has active links. Also check to make sure another gang ABD is not added to a gang ABD.
