Instead of checking the .bdrv_co_create_opts to see if we need the failback,

just implement the .bdrv_co_create_opts in the drivers that need it.
This way we don't break various places that need to know if the underlying
protocol/format really supports image creation, and this way we still
allow some drivers to not support image creation.
Fixes: fd17146cd93d1704cd96d7c2757b325fc7aac6fd
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1816007
Note that technically this driver reverts the image creation failback
fallback
for the vxhs driver since I don't have a means to test it,
and IMHO it is better to leave it not supported as it was prior to
generic image creation patches.
Also drop iscsi_create_opts which was left accidently
accidentally
