Incorrect #ifdef in arch/x86/mm/pat.c

[Dheeraj Reddy <dheerajr@gmail.com>]

Hello there,
    The checks for reading /dev/kmem and /dev/mem in arch/x86/mm/pat.c seems to 
be incorrect when CONFIG_STRICT_DEVMEM is set.
Following patch corrects it.
The check should always return 1 when CONFIG_STRICT_DEVMEM is not defined, 
similar to what is in drivers/char/mem.c
