Before this PR, when evaluating lease transfers or requests we'd check whether the evaluating replica could receive the lease rather than the acquiring replica. This patch fixes that bug by checking the state of the correct replica. Release note (bug fix): The system no longer erroneously transfers leases to replicas which are in the process of being removed which can lead to ranges being effectively unavailable due to an invalid lease.
