include/linux/mm.h: fix typo in VM_MPX definition
There's a typo in recent change of VM_MPX definition. We want it to be
VM_HIGH_ARCH_4, not VM_HIGH_ARCH_BIT_4.
This bug does cause visible regressions. In arch_vma_name the vmflags
are tested against VM_MPX. With the incorrect value of VM_MPX, a number
of vmas (such as the stack) test positive and end up being marked as
"[mpx]" in /proc/N/maps instead of their correct names.
This confuses tools like rr which expect to be able to find familiar
vmas.
Fixes: df3735c5b40f ("x86,mpx: make mpx depend on x86-64 to free up VMA flag")
