block: Allow changing 'detect-zeroes' on reopen
'detect-zeroes' is one of the basic BlockdevOptions available for all drivers, but it's not handled by bdrv_reopen_prepare(), so any attempt to change it results in an error: (qemu) qemu-io virtio0 "reopen -o detect-zeroes=on" Cannot change the option 'detect-zeroes' Since there's no reason why we shouldn't allow changing it and the implementation is simple let's just do it.
