    x86: prevent stale state of c1e_mask across CPU offline/online

Introduced a compile failure into the 32 bit x86 path:

arch/x86/kernel/process_32.c: In function 'cpu_exit_clear':
arch/x86/kernel/process_32.c:91: error: implicit declaration of function
'c1e_remove_cpu'
make[1]: *** [arch/x86/kernel/process_32.o] Error 1

because the prototype for c1e_remove_cpu() gets put into asm/idle.h but
this isn't directly included in process_32.c

Fix by making this a direct include.
