RDMA: Restore ability to fail on AH destroy
Like any other IB verbs objects, AH are refcounted by ib_core. The release
of those objects are controlled by ib_core with promise that AH destroy
can't fail.
Being SW object for now, this change makes dealloc_ah() to behave like any
other destroy IB flows.
Fixes: d345691471b4 ("RDMA: Handle AH allocations by IB/core")
