x86/mm/init: Pass unconverted symbol addresses to free_init_pages()
The x86 code has several places where it frees parts of kernel image:
1. Unused SMP alternative
2. __init code
3. The hole between text and rodata
4. The hole between rodata and data
We call free_init_pages() to do this. Strangely, we convert the symbol
addresses to kernel direct map addresses in some cases (#3, #4) but not
others (#1, #2).
The virt_to_page() and the other code in free_reserved_area() now works
fine for for symbol addresses on x86, so don't bother converting the
addresses to direct map addresses before freeing them.
