btrfs-progs: fix defrag -c option parsing

Browse Source 
The refactoring f3a132fa1b ("btrfs-progs: factor out compression type
name parsing to common utils") caused a bug with parsing option -c with
defrag:

  # btrfs fi defrag -v -czstd file
  ERROR: unknown compression type: zstd

  # btrfs fi defrag -v -clzo file
  ERROR: unknown compression type: lzo

  # btrfs fi defrag -v -czlib file
  ERROR: unknown compression type: zlib

Fix it by properly checking the value representing unknown compression
algorithm.

Issue: #403
