cciss: make fair timeouts during initialization

Patch makes fair initialization timeouts in cciss driver.

-----------------------------------
cciss driver has following code for timeouts during board initialization:

       ...
       for(i=0;i<MAX_CONFIG_WAIT;i++) {
               ...
               set_current_state(TASK_INTERRUPTIBLE);
               schedule_timeout(10);
       }
       ...

We compile cciss driver into the kernel and thus at the kernel boot schedule_timeout() returns very quickly and resulted timeouts became insufficient for correct board initialization. Particularly, we often got following error:
--
HP CISS Driver (v 2.6.8)
cciss: Device 0x46 has been found at bus 6 dev 1 func 0
cciss: unable to get board into simple mode
cciss: probe of 0000:06:01.0 failed with error -1
--

The patch is designed to make fair initialization timeouts.

----------
Hope, you'll check this changes and find them usefull. :) Kernel with patch was compiled and tested on two nodes. This patch is against mainstream 2.6.16-rc5 kernel.
