[PATCH 4.19] iwlwifi: 1000: set the TFD queue size

[PATCH 4.19] iwlwifi: 1000: set the TFD queue size

[Luca Coelho]

From: Pavel Machek <pavel@ucw.cz>

.max_tfd_queue_size was ommited for 1000 card serries leading to oops in
swiotlb.

Fixes: 7b3e42ea2ead ("iwlwifi: support multiple tfd queue max sizes for different devices")
