floss: Adds INTEROP_UPDATE_HID_SSR_MAX_LAT for Bornd C170B 

The bornd mouse has issue when it's in sniff subrating. The negotiated
max_lat value is not working and cause the mouse lag. This adds a new
sysprop entry to overwrite the max_lat to 0 when using bornd mouse.

Bug: 272143185
Tag: #floss
Test: m Bluetooth && manually test on bornd mouse
