Brian Behlendorf 1efdc45ea8 Fix O_APPEND open(2) flag 
As described in flags section of open(2):

  O_APPEND:
    The  file  is  opened in append mode.  Before each write(2), the
    file offset is positioned at the end of the  file,  as  if  with
    lseek(2).   O_APPEND may lead to corrupted files on NFS filesys-
    tems if more than one process appends data to a  file  at  once.
    This is because NFS does not support appending to a file, so the
    client kernel has to simulate it, which can't be done without  a
    race condition.

This issue was originally overlooked because normally the generic
VFS code handles this for a filesystem.  However, because ZFS explictly
registers a zpl_write() function it's responsible for the seek.
