NFSv4: Fix problem with OPEN_DOWNGRADE
RFC 3530 states that for OPEN_DOWNGRADE "The share_access and share_deny bits specified must be exactly equal to the union of the share_access and share_deny bits specified for some subset of the OPENs in effect for current openowner on the current file. Setattr is currently violating the NFSv4 rules for OPEN_DOWNGRADE in that it may cause a downgrade from OPEN4_SHARE_ACCESS_BOTH to OPEN4_SHARE_ACCESS_WRITE despite the fact that there exists no open file with O_WRONLY access mode. Fix the problem by replacing nfs4_find_state() with a modified version of nfs_find_open_context(). Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
