btrfs: simplify WQ_HIGHPRI handling in struct btrfs_workqueue
Just let the one caller that wants optional WQ_HIGHPRI handling allocate
a separate btrfs_workqueue for that. This allows to rename struct
__btrfs_workqueue to btrfs_workqueue, remove a pointer indirection and
separate allocation for all btrfs_workqueue users and generally simplify
the code.
