  sheep: change a condition of refreshing inode for read requests

Current condition of refreshing inode for read requests cannot handle
a case of reading readonly objects from snapshot. In such a case,
immediate refreshing isn't required.

(A case of reading from obsolete snapshot inode is handled in tgtd.)

  sheep: change a condition of refreshing inode for snapshot access

Even requests are issued to snapshot VDIs, refreshing is required for
handling a case of snapshot -> write something -> iSCSI multipath
failover.

Even refreshing requests are issued for snapshot VDIs, they must cause
validation.
