Fix TX stall when skipping netmapemu qdisc

Commit e6685fea679a ("Prevent tc configs from applying for generic
netmap adapter") skipped calling nm_os_catch_tx() to avoid installing
the custom netmapemu qdisc and hooking ndo_start_xmit().
However, gna->txqdisc is still set to 1 by nm_os_generic_set_features
so the tx sync path expects the qdisc to still be enabled.

Normally every mbuf sent by nm_os_generic_xmit_frame() is marked with
NM_MAGIC_PRIORITY_TX and generic_ndo_start_xmit() resets that priority
to 0 once the real driver transmits the packet.
Without the hook installed, the priority is never cleared.
generic_netmap_tx_clean() checks MBUF_QUEUED() to decide if a slot is
free and with txqdisc=1 and the priority permanently set, every slot
appears as in-use and the TX ring fills up and traffic stops.

To fix this, turn off the txqdisc flag if we are skipping qdisc setup.

mvpp2: Keep irqs_enabled in sync with interrupt status

If interrupts were disabled prior to an admin down/up, irqs_enabled
will be out of sync with the interrupt status when the interface
comes back up. This is now corrected when processing an interrupt.
