directly use kmalloc() and kfree() in init/initramfs.c
Instead of using the malloc() and free() wrappers needed by the lib/inflate.c code for allocations, simply use kmalloc() and kfree() in the initramfs code. This is needed for a further lib/inflate.c-related cleanup patch that will remove the malloc() and free() functions. Take that opportunity to remove the useless kmalloc() return value cast. Based on work done by Matt Mackall.
