[PATCH] kernel: timer: looping issue, need reset variable 'found'

[Chen Gang <gang.chen@asianux.com>]

According to __internal_add_timer(), in _next_timer_interrupt(), when
'tv1.vec' find one, but need 'cascade bucket(s)', we still need find
each slot of 'tv*.vec'.

So need reset variable 'found', so can fully scan ''do {...} while()''
for 'tv*.vec'.
