[ Upstream commit f7a594e40517fa2ab25d5ca10e7b6a158f529fb5 ]
There could be configs where some UMC instances are harvested. This
information is obtained through discovery data and populated in
umc.active_mask. Avoid reassigning this as AID mask, instead use the
mask directly while iterating through umc instances. This is to avoid
accesses to harvested UMC instances.

So set the err_addr to NULL to avoid the warnings.
