What is the expected behavior?

When the sniff/unsniff commands are sent (Host device is a Nintendo Switch here), the HID/ACL connections are severed.

What is the actual behavior?

Simply disabling the btm_pm_proc_mode_change function by performing an early return causes this issue to go away.

I'm not sure if there's a custom HCI command that is being misinterpreted as sniff/unsniff, but these are common commands and it seems like something is not right here with how the commands are being handled.

Steps to reproduce.

I'm not sure if there will be a simple way to reproduce this. I'm open to ideas, if there's another setup where we can test the sniff/unsniff commands in the context of a Bluetooth HID device.
