Wei Hu (Xavier) 2de74dcfbd net/hns3: fix MSI-X interrupt during initialization 
Currently, based on hns3 VF device error may occur during initialization.

The root cause as below:
When the following formula is executed during initialization, the
private variable named hw->tqps_num has not been obtained from PF driver
through mailbox, further causes failure when mapping interrupt and
queues.
  hw->num_msi = (num_msi > hw->tqps_num + 1) ? hw->tqps_num + 1 : num_msi;
We need to use hw->tqp_num after it is correctly assigned.

On the other hand, because the private variable named hw->num_msi, which
represents the number of MSI-x interrupt of hns3 PF/VF device, is used in
the '.get_reg' ops implementation function to dump all interrupt related
registers, it should be obtained from firmware directly and we'd better
not modify it in the driver.
