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.
