ath10k: fix kernel panic, move arvifs list head init before htt init
It is observed that while loading and unloading ath10k modules
in an infinite loop, before ath10k_core_start() completion HTT
rx frames are received, while processing these frames,
dereferencing the arvifs list code is getting hit before
initilizing the arvifs list, causing a kernel panic.
This patch initilizes the arvifs list before initilizing htt.
Fixes the below issue:
[<bf88b058>] (ath10k_htt_rx_pktlog_completion_handler+0x278/0xd08 [ath10k_core])
[<bf88b058>] (ath10k_htt_rx_pktlog_completion_handler [ath10k_core])
