wifi: ath12k: fix out-of-bound access of qmi_invoke_handler()
Currently, there is no terminator entry for ath12k_qmi_msg_handlers hence facing below KASAN warning,
================================================================== BUG: KASAN: global-out-of-bounds in qmi_invoke_handler+0xa4/0x148 Read of size 8 at addr ffffffd00a6428d8 by task kworker/u8:2/1273

The address belongs to the variable: ath12k_mac_mon_status_filter_default+0x4bd8/0xfffffffffffe2300 [ath12k] [...]
Add a dummy terminator entry at the end to assist the qmi_invoke_handler() in traversing up to the terminator entry without accessing an out-of-boundary index.
