RDMA/hns: Fix GMV table pagesize
[ Upstream commit ee045493283403969591087bd405fa280103282a ]
GMV's BA table only supports 4K pages. Currently, PAGESIZE is used to
calculate gmv_bt_num, which will cause an abnormal number of gmv_bt_num
in a 64K OS.
Fixes: d6d91e46210f ("RDMA/hns: Add support for configuring GMV table")
