6.6-stable review patch. If anyone has any objections, please let me know.

commit 3a931e9b39c7ff8066657042f5f00d3b7e6ad315 upstream.
We call btrfs_zone_finish_one_bg() to zone finish one block group and make room to activate another block group. Currently, we can choose a metadata block group as a target. But, as we reserve an active metadata block group, we no longer want to select a metadata block group. So, skip it in the loop.
