Subject: [PATCH 3.18 057/144] NFSv4: Remove incorrect check in can_open_delegated()

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

[ Upstream commit 4e379d36c050b0117b5d10048be63a44f5036115 ]

Remove an incorrect check for NFS_DELEGATION_NEED_RECLAIM in
can_open_delegated(). We are allowed to cache opens even in
a situation where we're doing reboot recovery.
