[ 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>
