[Tarantool-patches] [PATCH v4 01/11] recovery: do not call recovery_stop_local inside recovery_delete

Recovery stop local raises an exception in case of an recovery error
so it is not safe to stop recovery inside recovery delete and guard
inside local_recovery. So call recovery_stop_local manually.

Part of #980
