wifi: ath12k: fix out-of-bound access of qmiinvokehandler()

Currently, there is no terminator entry for ath12kqmimsg_handlers hence facing below KASAN warning,

================================================================== BUG: KASAN: global-out-of-bounds in qmiinvokehandler+0xa4/0x148 Read of size 8 at addr ffffffd00a6428d8 by task kworker/u8:2/1273

Add a dummy terminator entry at the end to assist the qmiinvokehandler() in traversing up to the terminator entry without accessing an out-of-boundary index.
