RDMA/hns: Fix insufficient extend DB for VFs.

Browse source

[ Upstream commit 0b8e658f70 ]

VFs and its PF will share the memory of the extend DB. Currently,
the number of extend DB allocated by driver is only enough for PF.
This leads to a probability of DB loss and some other problems in
scenarios where both PF and VFs use a large number of QPs.
