Bump the timeout for an "ordered tag" recovery action from 1 to 5 seconds.

Remove the multiple timeout panic.  Its very easy to get into a situation
where a timedout command will time out a second time even though the
recovery code is working fine.  A good example is:

1) Command times out during recovery
2) reset the timeout for the command
3) Recovery actions complete and all transactions are requeued
4) second timeout fires off which puts us back into recovery bogusly
5) another transaction that timedout once during the first recovery action
   times out causing the panic.

In essence, the correct solution to the problem is to put every transaction
back up into the work queue and have their timeout handling done in the same
way that all commands are handled.  The CAM layer makes this easy, so it
will have to wait until then.
