RDMA/hns: Fix insufficient extend DB for VFs.

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.
