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.
