[PATCH v1 1/1] x86/pat: Guard within_inclusive() with ifdeffery

[Andy Shevchenko]

The within_inclusive() in some cases, when CONFIG_X86_64=n, may be not used.
This, in particular, prevents kernel builds with clang, `make W=1`
and CONFIG_WERROR=y:

arch/x86/mm/pat/set_memory.c:215:1: error: unused function 'within_inclusive' [-Werror,-Wunused-function]

Fix this by guarding the definitions with the respective ifdeffery.

See also commit 6863f5643dd7 ("kbuild: allow Clang to find unused static
inline functions for W=1 build").
