 Modified Files:
        src/sys/ufs/ffs: ffs_snapshot.c
 
 Log Message:
 ffs_copyonwrite():   Only use si_snapblklist if it is already allocated.
 
 ffs_snapshot_read(): Use IO_ALTSEMANTICS to allow reading a snapshot vnode
                      beyond file system size.  Needed to read the snapblklist
                      on mount.
 
 Persistent snapshots work again.
 
 Should fix PR kern/37425: fss_snapshot_mount panic during fsck.
