[sheepdog] [PATCH 1/2] sheep: change a condition of refreshing inode for read requests

[Hitoshi Mitake]

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.)
