Subject: Bluetooth: msft: fix null pointer deref on msft_monitor_device_evt
Patch-mainline: v5.18-rc1
Git-commit: 5201d23cc8e57531e0b17e41c0ae10405ba6abd3
References: jsc#PED-1407
msft_find_handle_data returns NULL if it can't find the handle.
Therefore, handle_data must be checked, otherwise a null pointer
is dereferenced.
