Subject: [PATCH 05/27] net/ena: add reset reason in Rx error

[ upstream commit 9b260dbf7412819f9a5fc544872b1447d6938afe ]

Whenever the driver will receive too many descriptors from the device,
it should trigger the device reset with reset reason set to
ENA_REGS_RESET_TOO_MANY_RX_DESCS.

Fixes: 241da076b1f7 ("net/ena: adjust error checking and cleaning")
