[patch V2 01/17] Documentation: Remove bogus claim about del_timer_sync()

[Thomas Gleixner <tglx@linutronix.de>]

del_timer_sync() does not return the number of times it tried to delete the
timer which rearms itself. It's clearly documented:

 The function returns whether it has deactivated a pending timer or not.

This part of the documentation is from 2003 where del_timer_sync() really
returned the number of deletion attempts for unknown reasons. This code
was rewritten in 2005, but the documentation was not updated.
