x86, microcode, AMD: Replace vmalloc+memset with vzalloc
We don't have to do memset() ourselves after vmalloc() when we have vzalloc(), so change that in arch/x86/kernel/microcode_amd.c::get_next_ucode(). Signed-off-by: Jesper Juhl <jj@chaosbits.net> Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
