The usage of a cmpxchg loop in get_next_handle() is unnecessary, as the same
can be achieved with an atomic increment, which is both simpler to read, and
avoid any need for a loop.
The cmpxchg usage is likely a remnant of 32bit support, which didn't have an
instruction to do an atomic 64bit add, and instead a cmpxchg had to be used.
