ath10k: add support for MSDU IDs for USB devices

commit 93bbdec6683e1c8ba2cc4e6 ("ath10k: htt: support MSDU ids with
SDIO") introduced MSDU ID allocation in the htt TX path for high latency
devices. This feature needs to be enabled for USB as well in order to
have a functional TX path.

Tested-on: QCA9377 hw1.0 USB 1.0.0.299
