Subject: RDMA/cxgb4: Annotate r2 and stag as __be32

From: Leon Romanovsky <leon@kernel.org>


[ Upstream commit 7d7d065a5eec7e218174d5c64a9f53f99ffdb119 ]

Chelsio cxgb4 HW is big-endian, hence there is need to properly
annotate r2 and stag fields as __be32 and not __u32 to fix the
following sparse warnings.

  drivers/infiniband/hw/cxgb4/qp.c:614:16:
    warning: incorrect type in assignment (different base types)
      expected unsigned int [unsigned] [usertype] r2
      got restricted __be32 [usertype] <noident>
  drivers/infiniband/hw/cxgb4/qp.c:615:18:
    warning: incorrect type in assignment (different base types)
      expected unsigned int [unsigned] [usertype] stag
      got restricted __be32 [usertype] <noident>
