ipmi: set schedule_timeout_wait() value back to one

ipmi: set schedule_timeout_wait() value back to one

Fix a regression introduced by 482eac60bbef ("ipmi: add parameter to limit
CPU usage in kipmid").

Some systems were seeing CPU usage go up dramatically with the recent
changes to try to reduce timer usage in the IPMI driver.  This was traced
down to schedule_timeout_interruptible(1) being changed to
schedule_timeout_interruptbile(0).  Revert that part of the change.
