dm array: fix a reference counting bug in shadow_ablock
commit ed9571f0cf1fe09d3506302610f3ccdfa1d22c4a upstream.
An old array block could have its reference count decremented below
zero when it is being replaced in the btree by a new array block.
The fix is to increment the old ablock's reference count just before
inserting a new ablock into the btree.
