btrfs: zoned: fix zone_unusable accounting on making block group read-write again
This patch results in a variety of problems with the parisc64 qemu emulation.
Some examples from various test runs:

Reverting it fixes the problem.
Bisect log is attached for reference.
I tried to repeat the test with v6.1.105-rc1, but that fails to compile for parisc64.
/home/groeck/src/linux-stable/include/linux/slab.h:228: warning: "ARCH_KMALLOC_MINALIGN" redefined
228 | #define ARCH_KMALLOC_MINALIGN ARCH_DMA_MINALIGN
This is due to commit 96423e23e05b ("parisc: fix a possible DMA corruption").
After reverting that patch I don't see the above problems anymore in v6.1.105-rc1,
so it looks like the btrfs patches in v6.1.105-rc1 may have fixed it (or maybe
there is another hidden bug in the parisc64 qemu emulation).
