directly use kmalloc() and kfree() in init/initramfs.c

Browse Source 
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.
