6 years agobtrfs-progs: test: fix name generation not to contain trailing spaces

First patch causes test-convert fails.  This is because
generate_dataset() creates a name containing trailing spaces for

[Bug]
If using mkfs.btrfs with "-r" parameter and specified directory has
fifo/socket/char/block special file, then created filesystem can't pass
fsck:

------

[Reason]
Btrfs dir items/indexes records inode type, while "-r" only handles
directories, regular files and symlink, it makes such special files type
