viced: Unused sentinel in h_stateVerifyUuuidHash

The 'found' sentinel in h_stateVerifyUuidHash is unused, because
as soon as we set it, we jump out to the 'done' label. Simplify the
function's logic, and remove a static analysis warning, by just
removing the variable.

budb: Simplify scanHashTableBlock

We don't need to maintain two copies (entryAddr and nextEntryAddr)
of the entry address - rework the while loop so we just use one,
and make clang a little happier
