Btrfs: Remove unnecessary finish_wait() in wait_current_trans()

By the way, this patch makes code of waiting loop similar to example in wait.h(no functional change) Signed-off-by: Zhao Lei <zhaolei@cn.fujitsu.com> Signed-off-by: Miao Xie <miaox@cn.fujitsu.com> Signed-off-by: Chris Mason <chris.mason@oracle.com>
