[libvirt] [PATCH 6/9] virtime: Resolve Coverity DEADCODE

[John Ferlan]

Coverity complains that because of how 'offset' is initialized to
0 (zero), the resulting math and comparison on rem is pointless.

For the "while (rem < 0)", the value of 'rem' must be between
0 and 86399 (SECS_PER_DAY = 86400ULL). Thus, the addition of
offset (0) does nothing and the while (rem < 0) is pointless.

For the "while (rem > SECS_PER_DAY)", we have the same issue.
