x86: make movsl_mask definition non-CPU specific
movsl_mask is currently defined in arch/x86/kernel/cpu/intel.c, which contains code specific to Intel CPUs. However, movsl_mask is used in the non-CPU specific code in arch/x86/lib/usercopy_32.c, which breaks the compilation when support for Intel CPUs is compiled out. This patch solves this problem by moving movsl_mask's definition close to its users in arch/x86/lib/usercopy_32.c.
