dmfilemapd: return error for wrong number of args

Browse Source 
The initial check on argc incorrectly returns 1 when the wrong
number of arguments are present, causing a segfault in main()
when no arguments are given:

  # dmfilemapd
  Wrong number of arguments.
  usage: dmfilemapd <fd> <group_id> <path> <mode> [<foreground>[<log_level>]]
  Segmentation fault (core dumped)
