wifi: ath10k: fix the stack frame size warning in ath10k_remain_on_channel
Fix the following W=1 kernel build warning:
drivers/net/wireless/ath/ath10k/mac.c: In function ‘ath10k_remain_on_channel’:
drivers/net/wireless/ath/ath10k/mac.c:7980:1: warning: the frame size of 1064 bytes is larger than 1024 bytes [-Wframe-larger-than=]
Compile tested only.
