kmemleak: Add support for NO_BOOTMEM configurations
With commits 08677214 and 59be5a8e, alloc_bootmem()/free_bootmem() and friends use the early_res functions for memory management when NO_BOOTMEM is enabled. This patch adds the kmemleak calls in the corresponding code paths for bootmem allocations.
