Remove the ib_is_destroyable_retryable() concept.
The idea here was to allow the drivers to forcibly clean the HW object
even if they otherwise didn't want to (eg because of usecnt). This was an
attempt to clean up in a world where drivers were not allowed to fail HW
object destruction.
Now that we are going back to allowing HW objects to fail destroy this
doesn't make sense. Instead if a uobject's HW object can't be destroyed it
is left on the uobject list and it is up to uverbs_destroy_ufile_hw() to
clean it. Multiple passes over the uobject list allow hidden dependencies
to be resolved. If that fails the HW driver is broken, throw a WARN_ON and
leak the HW object memory.
All the other tricky failure paths (eg on creation error unwind) have
already been updated to this new model.

For RDMA TX flow table, set destination type to be 'port' and prevent
creation of flows with TIR destination.
As RDMA TX is an egress flow table the rules on this flow table should
not forward traffic back to the NIC and should set the destination to be
the port.
Without the setting of this destination type flow rules on the RDMA TX
flow tables are not created as FW invokes a syndrome for undefined
destination for the rule.
