Revert "rpcd: update to git HEAD"

This reverts commit 190e7939639846b86ab487c50169963382720e2b.

This update introduces a potential null-pointer deref with subsequent rpcd
crash when querying wireless info for non-nl80211 wdevs.

Additionally it wrongly includes ht frequency information for non-ht BSSes.
