History
Bruce Evans d02601f8cf Fixed rev.1.81. mp->mnt_kern_flag was restored in the non-error case of 
`mount -u'.  This only matters for `mount -u' competing with unmounts.
If I understand the locking correctly: if mount() blocks, then unmount()
may run and set mp->kern_flag for the same mp.  Then unmount() blocks
waiting for mount() to finish.  When unmount() continues, its MNTK flags
(MNTK_UNMOUNT and MNTK_MWAIT) may have been clobbered.

Didn't fix old bugs:
- restoring mp->mnt_kern_flag is wrong for the same reasons in the error
  case.
- the error case of unmount() seems to be broken too:
  (a) MNTK_UNMOUNT gets clobbered, although another unmount() may have
      set it.  Perhaps it shouldn't be set until after the full lock is
      aquired.
  (b) MNTK_MWAIT isn't honoured.

Fixed a nearby style bug.
