mm: remove arch_bprm_mm_init() hook
From: Dave Hansen <dave.hansen@linux.intel.com>
MPX is being removed from the kernel due to a lack of support
in the toolchain going forward (gcc).
arch_bprm_mm_init() is used at execve() time. The only non-stub
implementation is on x86 for MPX. Remove the hook entirely from
all architectures and generic code.
