btrfs: zoned: do not select metadata BG as finish target

Browse Source 
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.
