[PATCH v2] btrfs: fix typos and repeated words in comments

[Hemanth Selam]

Fix misspellings and repeated words in comments, found with
scripts/checkpatch.pl and codespell.  Only touches comments, no code
changes.

Changes since v1:
 - the typo and repeated-word patches are folded into one, as they only
   touch comments
 - rebased onto btrfs for-next
 - picked up the further typos codespell found, which David Sterba
   listed: Temporarilly, Checksume, coresponding, caclulated, wheather
   and cannnot ("commited" in block-group.h was already fixed by v1)
