[PATCH] x86/resctrl: Fix typos in mba_sc mount option

[Xiaochen Shen]

With mount option "mba_MBps", we could enable MBA Software Controller
(mba_sc) to specify MBA memory bandwidth in unit MBps (Mega Bytes per
second). See details in Documentation/x86/resctrl_ui.txt.

Commit 23bf1b6be9c2 ("kernfs, sysfs, cgroup, intel_rdt: Support
fs_context") changes the mount option from "mba_MBps" to "mba_mpbs" by
mistake.

Change back from "mba_mpbs" to "mba_MBps", and rename Opt_mba_mpbs to
Opt_mba_mbps.

Fixes: 23bf1b6be9c2 ("kernfs, sysfs, cgroup, intel_rdt: Support fs_context")
