Xie XiuQi 471bfba87f ipmi: fix timeout calculation when bmc is disconnected ...

commit e21404dc0a upstream.

Loading ipmi_si module while bmc is disconnected, we found the timeout
is longer than 5 secs.  Actually it takes about 3 mins and 20
secs.(HZ=250)

error message as below:
  Dec 12 19:08:59 linux kernel: IPMI BT: timeout in RD_WAIT [ ] 1 retries left
  Dec 12 19:08:59 linux kernel: BT: write 4 bytes seq=0x01 03 18 00 01
  [...]
  Dec 12 19:12:19 linux kernel: IPMI BT: timeout in RD_WAIT [ ]
  Dec 12 19:12:19 linux kernel: failed 2 retries, sending error response
  Dec 12 19:12:19 linux kernel: IPMI: BT reset (takes 5 secs)
  Dec 12 19:12:19 linux kernel: IPMI BT: flag reset [ ]

Function wait_for_msg_done() use schedule_timeout_uninterruptible(1) to
sleep 1 tick, so we should subtract jiffies_to_usecs(1) instead of 100
usecs from timeout.
