zfs does not honor NFS sync write semantics
The linux kernel's nfsd implementation use RWF_SYNC to determine if the
write is synchronous or not. This flag is used to set the kernel's I/O
control block flags. Unfortunately, ZFS was not updated to inspect these
flags so NFS sync writes were not being honored.
This change maps the IOCB_* flags to the ZFS equivalent.
