ck_epoch: Remove redundant e + 2 observation.
...
This inefficiency was introduced in the overhaul of
the ck_epoch API.
Synchronize is executed with respect to e. At e + 1,
references can only exist to objects logically deleted
at e or e + 1. At e + 2, however, references can only exist to
objects logically deleted at e + 1 and e + 2. In the case that a
thread observes an out of date epoch value, an increment to the
global epoch would fail as the active bit is ordered with respect
to the memory barrier in synchronize. In the case that a protected
section begins after the memory barrier, then it is guaranteed
to not acquire the hazardous reference.
This does not change granularity of deferral lists, however.
There is still a requirement of 3 deferral lists on the fast path
(4 in ck_epoch for fast path purposes) as at any moment, any given
deferral list for value e can contain references to objects with
active references from both e and e - 1.
