* wdclient: keep a shared volume lookup alive when its first caller leaves

Concurrent misses for the same volumes share one provider lookup, but it
ran on the first caller's context, so that caller's cancellation failed
every request waiting on it. The lookup now runs on a context no single
caller can cancel, and each caller stops waiting when its own context ends.

* wdclient: wait for the second caller to join before canceling the first

A fixed sleep did not prove the second caller had joined the shared lookup:
a late caller could hit the filled cache and pass without waiting. The test
now waits until the caller reads its own Done channel, which happens only
after DoChan registered it.
