x86, cpa: dont use large pages for kernel identity mapping with DEBUG_PAGEALLOC

commit 0b8fdcbcd287a1fbe66817491e6149841ae25705 upstream.

Don't use large pages for kernel identity mapping with DEBUG_PAGEALLOC.
This will remove the need to split the large page for the
allocated kernel page in the interrupt context.

This will simplify cpa code(as we don't do the split any more from the
interrupt context). cpa code simplication in the subsequent patches.
