hodec2: cosmetic: clarify ho_candidate.{current,target}

So far it is often confusing which cell a specific member refers to.
Clarify lchan, bts, ... to current.lchan, target.bts, ...

Also move the rxlev_{current,target} to {current,target}.rxlev.

Eliminate numerous local variables to make it easier to read which side
is being used (e.g. "c->target.bts" instead of just "bts").

No functional change.
