Subject: [PATCH 3/6] scsi: ufs: use WQ_HIGHPRI for gating work

From: Jaegeuk Kim <jaegeuk@...gle.com>

Must have WQ_MEM_RECLAIM
``WQ_MEM_RECLAIM``
  All wq which might be used in the memory reclaim paths **MUST**
  have this flag set.  The wq is guaranteed to have at least one
  execution context regardless of memory pressure.
