wifi: ath12k: Decrease ath12k_mac_op_remain_on_channel() stack usage
Building the ath12k driver with llvm-18.1.7-x86_64 produces the warning:
drivers/net/wireless/ath/ath12k/mac.c:10028:12: warning: stack frame size (1080) exceeds limit (1024) in 'ath12k_mac_op_remain_on_channel' [-Wframe-larger-than]
A major contributor to the stack usage in this function is:
struct ath12k_wmi_scan_req_arg arg;
Avoid the excess stack usage by dynamically allocating arg instead of
declaring it on the stack. As part of the effort use __free() for both
this new allocation as well as the existing chan_list allocation, and
since then no central cleanup is required, replace all cleanup gotos
with returns.
