net: mana: Fix potential deadlocks in mana napi ops

When net_shaper_ops are enabled for MANA, netdev_ops_lock
becomes active.

MANA VF setup/teardown by netvsc follows this call chain:

netvsc_vf_setup()
        dev_change_flags()
		...
         __dev_open() OR __dev_close()

dev_change_flags() holds the netdev mutex via netdev_lock_ops.

Meanwhile, mana_create_txq() and mana_create_rxq() in mana_open()
path call NAPI APIs (netif_napi_add_tx(), netif_napi_add_weight(),
napi_enable()), which also try to acquire the same lock, risking
deadlock.

Similarly in the teardown path (mana_close()), netif_napi_disable()
and netif_napi_del(), contend for the same lock.

Switch to the _locked variants of these APIs to avoid deadlocks
when the netdev_ops_lock is held.
