[Devel] Tweak /proc/ipmi removal

[Alexey Dobriyan]

Driver does
	proc_mkdir("ipmi", NULL);
but
	remove_proc_entry(proc_ipmi_root->name, &proc_root);

This is OK and working if only slightly inconsistent.
Also changing proc_root to NULL will help OpenVZ which has
multiple proc roots and, as we now know, requires matching parents in
such cases.

Please, apply.
