net/mlx5e: Encapsulate updating netdev queues into a function

Browse source 
[ Upstream commit c2c95271f9 ]

As a preparation for one of the following commits, create a function to
encapsulate the code that notifies the kernel about the new amount of
RX and TX queues. The code will be called multiple times in the next
commit.
