net: netdev_queue: netdev_txq_completed_mb(): fix wake condition

Browse Source 
[ Upstream commit 894d750831 ]

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: c91c46de6b ("net: provide macros for commonly copied lockless queue stop/wake code")
