NFSD: Don't give out read delegations on creates
When an exclusive create is done with the mode bits set (aka open(testfile, O_CREAT | O_EXCL, 0777)) this causes a OPEN op followed by a SETATTR op. When a read delegation is given in the OPEN, it causes the SETATTR to delay with EAGAIN until the delegation is recalled. This patch caused exclusive creates to give out a write delegation (which turn into no delegation) which allows the SETATTR seamlessly succeed.
