net/ixgbe: fix Rx and Tx queue status

[ upstream commit 4a8490075692c32797be4280aea33772a5865038 ]

Ixgbevf driver don't enable queue start/stop functions, queue status is not
updated when the HW queue enabled or disabled. It caused application can't
get correct queue status.
This patch fixes the issue by updating the queue states when the queue is
disabled or enabled.

Fixes: 429c6d8 ("ixgbe: prepare for vector pmd")
Fixes: f0c50e5 ("ixgbe: move PMD specific fields out of base driver")
