Feng Ruohang 54186040ca test(restore): release the handed-over restore lock before reusing options
Three restore tests record the options of a POST's background restore
with a stub and restore with them later: TestRestoreAttemptGenerationFencing,
TestExpireRestoredUsesQuorumGeneration and TestRestoreHealNeedsRestoreQuorum.
The options carry the restore lock that POST hands to its worker. The
handler releases that lock only after the stub returns, while the test
proceeds as soon as the stub has signaled. When the test's restore
checked the lock before that release, it kept the lock, and the release
then canceled its context: every drive read failed with "context
canceled" and the restore reported insufficient read quorum.

Under -race this failed 11 times in 60 runs of the three tests on
69a4f938a, in the worker and old-reset modes of the fencing test and in
the multi-pool expiry test.

A new helper, restoreCaptureOptions, releases the lock before it records
the options, so a later restore takes it again, as a queued worker whose
lock ended does. TestRestoreSupersededAttempt already does this. With
the helper, the three tests passed 60 runs under -race.

Production code does not change: the handler's goroutine runs the
restore and releases the lock after it, and a lock lost during a
restore stops it as intended.
