Subject: [PATCH] ath10k: htt_tx: move lock into id_get function
Git-commit: e82f57c8b9708baf4a58a9282636d9285b5aa2dd
Patch-mainline: v4.19-rc1
References: FATE#326906

This is only code refactoring as all call sites of
ath10k_htt_tx_alloc_msdu_id() take the same lock it can be moved into the
id_get function and the assertion dropped.
