[Qemu-devel] [PULL 06/15] qcow2: remove extra local_error variable

[Kevin Wolf <kwolf@redhat.com>]

From: Alberto Garcia <berto@igalia.com>

Commit d7086422b1c1e75e320519cfe26176db6ec97a37 added a local_err
variable global to the qcow2_amend_options() function, so there's no
need to have this other one.
