Fix zil_commit() NULL dereference
Update the current code to ensure inodes are never dirtied if they are
part of a read-only file system or snapshot. If they do somehow get
dirtied an attempt will make made to write them to disk. In the case
of snapshots, which don't have a ZIL, this will result in a NULL
dereference in zil_commit().
