scripts/spelling.txt: Fix "mistake" version of "synchronization"

If both "mistake" version and "correction" version are the same, a warning
message is created by checkpatch which is impossible to fix. But it was
noticed that Colan Ian King created a commit e6c0a0889b80 ("ALSA: aloop:
Fix spelling mistake "synchronization" -> "synchronization"") which
suggests that this spelling mistake was fixed by replacing the word
"synchronization" with itself. But the actual diff shows that the mistake
in the code was "sychronization". It is rather likely that the "mistake"
in spelling.txt should have been the latter.

Fixes: 2e74c9433ba8 ("scripts/spelling.txt: add more spellings to spelling.txt")
