btrfs: Add trace for btrfs_workqueue alloc/destroy
Since most of the btrfs_workqueue is printed as pointer address, for easier analysis, add trace for btrfs_workqueue alloc/destroy. So it is possible to determine the workqueue that a given work belongs to(by comparing the wq pointer address with alloc trace event).
