memblock: replace free_bootmem{_node} with memblock_free

The free_bootmem and free_bootmem_node are merely wrappers for
memblock_free. Replace their usage with a call to memblock_free using the
following semantic patch:

@@
expression e1, e2, e3;
@@
(
- free_bootmem(e1, e2)
+ memblock_free(e1, e2)
|
- free_bootmem_node(e1, e2, e3)
+ memblock_free(e2, e3)
)
