btrfs: rename check_async_write and let it return bool
The 'check_async_write' function is a helper used in 'btrfs_submit_metadata_bio' and it checks if asynchronous writing can be used for metadata. Make the function return bool and get rid of the local variable async in btrfs_submit_metadata_bio storing the result of check_async_write's tests. As this is touching all function call sites, also rename it to should_async_write as this is more in line with the naming we use.
