[PATCH 4/7] net/cnxk: fix descriptor count update on reconfig

[Rahul Bhansali]

In Rx queue setup, input descriptors count is updated as per
requirement, and stored. But during port reconfig , this
descriptor count will change again in rx queue setup.
Hence, will need to store the initial input descriptor count.

Fixes: a86144cd9ded ("net/cnxk: add Rx queue setup and release")
