nfsd: use vfs_fsync_range(), not O_SYNC, for stable writes
NFSv4 shares the same struct file across multiple writes. (And we'd like NFSv2 and NFSv3 to do that as well some day.) So setting O_SYNC on the struct file as a way to request a synchronous write doesn't work. Instead, do a vfs_fsync_range() in that case.
