[Qemu-devel] [PATCH v2 06/13] qcow2: Move qcow2_update_options() call up

[Kevin Wolf <kwolf@redhat.com>]

qcow2_update_options() only updates some variables in BDRVQcowState and
doesn't really depend on other parts of it being initialised yet, so it
can be moved so that it immediately follows the other half of option
handling code in qcow2_open().
