bootmem: fix wrong call parameter for free_bootmem()
It is strange that alloc_bootmem() returns a virtual address and
free_bootmem() requires a physical address. Anyway, free_bootmem()'s
first parameter should be physical address.
There are some call sites for free_bootmem() with virtual address. So fix
them.
