[PATCH v4 27/31] net/ena: update device-preferred size of rings

[shaibran at amazon.com]

From: Shai Brandes <shaibran at amazon.com>

Update the device-preferred size of the Tx ring to fall within the
valid range when a large LLQ is enabled. For consistency, align the
device-preferred size of the Rx ring accordingly.
