Subject: [PATCH] lib/raid6: fix unnecessary rebuild of vpermxor*.c

The following four files are every time rebuilt:

  UNROLL  lib/raid6/vpermxor1.c
  UNROLL  lib/raid6/vpermxor2.c
  UNROLL  lib/raid6/vpermxor4.c
  UNROLL  lib/raid6/vpermxor8.c

I made a mistake in the Makefile refactoring.

Fixes: 72ad21075df8 ("lib/raid6: refactor unroll rules with pattern rules")
