doom: fix blazing door sounds (from qu7uux)

blazing doors are a "fast" door type with its own sound effects, introduced in
doom2. doom2 map 2 has one right at the beginning.

this fixes two bugs:
- when a closing blazing door is completely shut, the closing sound effect is
  erroneously played again (the first time being when it began closing). this
  gives the impression of two doors closing.
- when reopening a closing blazing door (standing underneath a blazing door
  while it's closing), the sound effect for regular doors opening is played,
  instead of the one for blazing doors, because of a missing case in the switch
  statement.
