[PATCH 6.18 030/333] workqueue: Use POOL_BH instead of WQ_BH when checking pool flags

[ Upstream commit f42f9091be9e5ff57567a3945cfcdd498f475348 ]

pr_cont_worker_id() checks pool->flags against WQ_BH, which is a
workqueue-level flag (defined in workqueue.h). Pool flags use a
separate namespace with POOL_* constants (defined in workqueue.c).
The correct constant is POOL_BH. Both WQ_BH and POOL_BH are defined
as (1 << 0) so this has no behavioral impact, but it is semantically
wrong and inconsistent with every other pool-level BH check in the
file.
