x86: mm: rename __is_kernel_text() to is_x86_32_kernel_text()
Commit b56cd05c55a1 ("x86/mm: Rename is_kernel_text to __is_kernel_text"),
add '__' prefix not to get in conflict with existing is_kernel_text() in
<linux/kallsyms.h>.
We will add __is_kernel_text() for the basic kernel text range check in
the next patch, so use private is_x86_32_kernel_text() naming for x86
special check.
