deleg: use SETATTR for OPEN4_CREATE

Browse source 
prevent an OPEN with OPEN4_CREATE from breaking a write delegation by sending a SETATTR instead
moved static function remove_unsupported_attrs() from setattr.c to nfs41_superblock_supported_attrs() in nfs41_superblock.c, now used by both setattr.c and delegation.c
