[PATCH v4 02/10] net/gve: fix DQO completion queue stall on unknown type

[Tathagat Priyadarshi]

When gve_tx_clean_dqo() sees an unknown completion type, it returns
without advancing complq_tail. Every later call stops at the same
entry, so Tx completions are never processed again.

Log the type and skip the entry.
