btrfs: zoned: let the for_treelog test in the allocator stand out
The statement which decides if an extent allocation on a zoned device is
for the dedicated tree-log block group or not and if we can use the block
group we picked for this allocation is not easy to read but an important
part of the allocator.
Rewrite into an if condition instead of a plain boolean test to make it
stand out more, like the version which tests for the dedicated
data-relocation block group.
