btrfs: zoned: do not enable async discard
The zoned mode need to reset a zone before using it. We rely on btrfs's
original discard functionality (discarding unused block group range) to do
the resetting.
While the commit 63a7cb130718 ("btrfs: auto enable discard=async when
possible") made the discard done in an async manner, a zoned reset do not
need to be async, as it is fast enough.
Even worth, delaying zone rests prevents using those zones again. So, let's
disable async discard on the zoned mode.
Fixes: 63a7cb130718 ("btrfs: auto enable discard=async when possible")
