[PATCH v2] block/file-posix: fix update_zones_wp() caller

[Sam Li]

When the zoned request fail, it needs to update only the wp of
the target zones for not disrupting the in-flight writes on
these other zones. The wp is updated successfully after the
request completes.

Fixed the callers with right offset and nr_zones.

Thanks, applied to my block branch:

https://gitlab.com/hreitz/qemu/-/commits/block

(Rebased on master, and I’ve also fixed the comment to read “boundaries” 
instead of “bounaries”.  Hope that’s OK!)

Thanks!
