btrfs: tests: fix formatting in btrfs-tests

checkpatch.pl had a couple of formatting suggestions:
- torvalds#38: Don't use multiple blank lines
- torvalds#42: Missing a blank line after declarations
- torvalds#282: Alignment should match open parenthesis

Fixed these format suggestions, checkpatch.pl is a little cleaner now.
