net: hns3: Fix for CMDQ and Misc. interrupt init order problem

Browse source 
When vf module is loading, the cmd queue initialization should
happen before misc interrupt initialization, otherwise the misc
interrupt handle will cause using uninitialized cmd queue problem.
There is also the same issue when vf module is unloading.

This patch fixes it by adjusting the location of some function.
