First patch fix copy paste typo in debug message in lzo.c, lzo is not deflate

Second and third patches force btrfs not compress data if compression will not 
free at least one PAGE_SIZE
Because it's useless in term of storage and read data from disk, as a result 
productivity suffers

Timofey Titovets (3):
  Btrfs: lzo.c pr_debug() deflate->lzo
  Btrfs: lzo compression must free at least PAGE_SIZE
  Btrfs: zlib compression must free at least PAGE_SIZE
