ipmi: ipmi_devintf: compat_ioctl method fails to take ipmi_mutex
commit 6368087e851e697679af059b4247aca33a69cef3 upstream.
When a 32 bit version of ipmitool is used on a 64 bit kernel, the
ipmi_devintf code fails to correctly acquire ipmi_mutex. This results in
incomplete data being retrieved in some cases, or other possible failures.
Add a wrapper around compat_ipmi_ioctl() to take ipmi_mutex to fix this.
