Fix RSSI offset for pre-msg RSSI notification

Browse Source 
last_rssi is a large negative number, with rssi_offset being +292,
intended to be added to put the value inside the range of a single byte uint.
Before sending the data message, a RSSI message is automatically sent,
which is quite nice, but the value ends up overflowing the 8-bit uint, giving
a bogus value.
