net: netdev_queue: netdev_txq_completed_mb(): fix wake condition

[ Upstream commit 894d7508316e7ad722df597d68b4b1797a9eee11 ]

netif_txq_try_stop() uses "get_desc >= start_thrs" as the check for
the call to netif_tx_start_queue().

Use ">=" i netdev_txq_completed_mb(), too.

Fixes: c91c46de6bbc ("net: provide macros for commonly copied lockless queue stop/wake code")
