  1. kvserver: read lease under mutex when switching lease type 

    A race could occur when a replica queue and post lease application both
attempted to switch the lease type. This race would cause the queue to
not process the replica because the lease type had already changed. As a
result, lease preference violations might not have been quickly
resolved by the lease queue.

Read the lease under the same mutex used for requesting the lease, when
possibly switching the lease type.
