ipmi: fix unsigned long underflow
commit 392a17b10ec4320d3c0e96e2a23ebaad1123b989 upstream.
When I set the timeout to a specific value such as 500ms, the timeout
event will not happen in time due to the overflow in function
check_msg_timeout:
...
ent->timeout -= timeout_period;
if (ent->timeout > 0)
return;
...
The type of timeout_period is long, but ent->timeout is unsigned long.
This patch makes the type consistent.
