Pass IO_NOMACCHECK to vn_rdwr() in the following checks to prevent
enforcement of MAC policy on the read or write operations:

- In ext2fs, don't enforce MAC on loop-back reads and writes supporting
  directory read operations in lookup(), directory modifications in
  rename(), directory write operations in mkdir(), symlink write
  operations in symlink().

- In the NFS client locking code, perform vn_rdwr() on the NFS locking
  socket without enforcing MAC, since the write is done on behalf of
  the kernel NFS implementation rather than the user process.

- In UFS, don't enforce MAC on loop-back reads and writes supporting
  directory read operations in lookup(), and symlink write operations
  in symlink().
