3.2.62-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Dave Chinner <dchinner@xxxxxxxxxx>
commit e3a746f5aab71f2dd0a83116772922fb37ae29d6 upstream.
The current cursor is reallocated when retrying the allocation, so
the existing cursor needs to be destroyed in both the restart and
the failure cases.
