Fix resources cleanup

When running "test_create_manage_and_write" test with
default share type (i.e. set default_share_type_name
= default in tempest.conf) it passed, however, when
there is no default share type it failed with
"Target share type is still in use."
This is because the failed managed share is not deleted
before the share type it is based on.
This patch makes sure the manila share is deleted before
its share type.
