wifi: ath11k: fix ath11k_mac_op_remain_on_channel() stack usage

Browse source

When compiling with clang 16.0.6, I've noticed the following:

drivers/net/wireless/ath/ath11k/mac.c:8903:12: warning: stack frame
size (1032) exceeds limit (1024) in 'ath11k_mac_op_remain_on_channel'
[-Wframe-larger-than]
static int ath11k_mac_op_remain_on_channel(struct ieee80211_hw *hw,
           ^
68/1032 (6.59%) spills, 964/1032 (93.41%) variables

So switch to kzalloc()'ed instance of 'struct scan_req_params' like
it's done in 'ath11k_mac_op_hw_scan()'. Compile tested only.
