thunderbolt: Add comment explaining return value of read_drom_entry_location ()

Browse Source 
During review it was pointed out that the return value of
read_drom_entry_location () should be documented because it also returns
TRUE when an entry was not found from the DROM. Caller needs to look for
the location->offset in that case. Add a comment explaining this.
