  Log:
  Fix another bug introduced with rev. 1.204; in vfs_donmount() if
  the 'vfs_getopt(optlist, "errmsg", (void **)&errmsg, &errmsg_len)'
  call fails, 'errmsg' is left uninitialized, making the later tests
  against NULL meaningless, and the uses bogus. Thus initialize
  'errmsg' to NULL beforehand. [1]
  While at it, remove the superfluous assignment of 0 to 'errmsg_len'
  if the above mentioned call fails as it's already initialized to 0.
