  1. storage: check whether the acquiring replica can receive the lease 

    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.
