wifi: ath12k: Decrease ath12k_bss_assoc() stack usage

Browse source

Currently when building ath12k with gcc-14.2.0 the following warning
is observed:

drivers/net/wireless/ath/ath12k/mac.c: In function 'ath12k_bss_assoc':
drivers/net/wireless/ath/ath12k/mac.c:3080:1: warning: the frame size of 1040 bytes is larger than 1024 bytes [-Wframe-larger-than=]

A major contributor to the stack usage in this function is:

	struct ath12k_wmi_peer_assoc_arg peer_arg;

Avoid the excess stack usage by dynamically allocating peer_arg
instead of declaring it on the stack.
