[PATCH] btrfs: use bio_is_zone_append() in the completion handler

[Christoph Hellwig <hch@xxxxxx>]

Otherwise it won't catch bios turned into regular writes by the block
level zone write plugging. The additional test it adds is for emulated
zone append.

Fixes: 9b1ce7f0c6f8 ("block: Implement zone append emulation")
