MIPS: SMTC: Fix lockup in smtc_distribute_timer

2009-11-13T17:10:38+00:00

1. At the end of smtc_distribute_timer, nextstamp is valid and has already
   passed so we goto repeat.
2. Nothing updates nextstamp (only updated if the timeout is in the future
   And we just decided it is in the past)
3. At the end nextstamp still has the same value so it is still valid and
   in the past.
4. This repeats until read_c0_count has a value which causes nextstamp to
   be in the future.
