x86/resctrl: Fix typos in the mba_sc mount option
The user can control the MBA memory bandwidth in MBps (Mega
Bytes per second) units of the MBA Software Controller (mba_sc)
by using the "mba_MBps" mount option. For details, see
Documentation/x86/resctrl_ui.txt.
However, commit
23bf1b6be9c2 ("kernfs, sysfs, cgroup, intel_rdt: Support fs_context")
changed the mount option name from "mba_MBps" to "mba_mpbs" by mistake.
Change it back from to "mba_MBps" because it is user-visible, and
correct "Opt_mba_mpbs" spelling to "Opt_mba_mbps".
