powerpc/32s: Fix module loading failure when VMALLOC_END is over 0xf0000000
In is_module_segment(), when VMALLOC_END is over 0xf0000000,
ALIGN(VMALLOC_END, SZ_256M) has value 0.
In that case, addr >= ALIGN(VMALLOC_END, SZ_256M) is always
true then is_module_segment() always returns false.
Use (ALIGN(VMALLOC_END, SZ_256M) - 1) which will have
value 0xffffffff and will be suitable for the comparison.
Fixes: c49643319715 ("powerpc/32s: Only leave NX unset on segments used for modules")
