[BLUETOOTH] net/bluetooth/hci_core.c: Use time_* macros
The functions time_before, time_before_eq, time_after, and
time_after_eq are more robust for comparing jiffies against other
values.
So following patch implements usage of the time_after() macro, defined
at linux/jiffies.h, which deals with wrapping correctly
