As discussed in the mailing list, renaming tm_disabled global variable since it has nothing to do with concept we have been using in tm_enable() and tm_enabled() functions. This will avoid a possible confusion that tm_enable() would change tm_disable variable. I am also taking the opportunity to change some comments that still reference old fields that were changed in commit 000ec280e3dd ("powerpc: tm: Rename transct_(*) to ck(\1)_state").
