[PATCH] SCSI, LSI Fusion MPT: Fix memory leak inmptctl_getiocinfo()

[Jesper Juhl]

Hi,

A 'kfree(karg)' is missing in a failure path in 
drivers/message/fusion/mptctl.c::mptctl_getiocinfo() which can cause a 
memory leak. This patch should take care of that.

Hope I didn't miss something obvious, but to me it looks like adding this 
kfree() is the right thing to do. If you disagree feel free to correct me 
:-)
