Merge zvol.c changes from PSARC 2010/306 Read-only ZFS pools
The changes to zvol.c were never merged from the last onnv_147
bulk update. This was because zvol.c was largely rewritten
for Linux making it fairly easy to miss these sorts of changes.
This causes a regression when importing a zpool with zvols
read-only. This does not impact pool which only contain
filesystem datasets.
