net: mana: guard TX wq object destroy with INVALID_MANA_HANDLE check

Browse source

[ Upstream commit f8fd56977e ]

mana_create_txq() has several error paths (after mana_alloc_queues() or
mana_create_wq_obj() failure) where tx_qp[i].tx_object stays as the
INVALID_MANA_HANDLE sentinel set at allocation. mana_destroy_txq() then
unconditionally calls mana_destroy_wq_obj() with (u64)-1, which firmware
rejects and logs an error.

Mirror the RX-side pattern in mana_destroy_rxq() and skip the destroy
when the handle is still INVALID_MANA_HANDLE.
