net: mana: Skip WQ object destruction for uninitialized RXQ
In mana_destroy_rxq(), mana_destroy_wq_obj() is called unconditionally
even when the WQ object was never created (rxobj is still
INVALID_MANA_HANDLE). When mana_create_rxq() fails before
mana_create_wq_obj() succeeds, the error path calls mana_destroy_rxq()
which sends a bogus destroy command to the hardware:
mana 7870:00:00.0: HWC: Failed hw_channel req: 0x1d
mana 7870:00:00.0: Failed to send mana message: -71, 0x1d
mana 7870:00:00.0 eth7: Failed to destroy WQ object: -71
Guard mana_destroy_wq_obj() with an INVALID_MANA_HANDLE check so that
mana_destroy_rxq() is safe to call at any stage of RXQ initialization.
Fixes: ca9c54d2d6a5 ("net: mana: Add a driver for Microsoft Azure Network Adapter (MANA)")
