block: Update bs->open_flags earlier in bdrv_open_common()

Browse Source 
We're only doing this immediately before opening the image, but
bs->open_flags is used earlier in the function. At the moment this is
not causing problems because none of the checked flags are modified by
update_flags_from_options(), but this will change when we introduce
the "read-only" option.

This patch calls update_flags_from_options() at the beginning of the
function, immediately after creating the QemuOpts.
