Mike Rapoport (Microsoft) 25ee3aff99 powerpc: fadump: pair alloc_pages_exact() with free_pages_exact() ...

fadump allocates buffers with alloc_pages_exact(), but then marks them
as reserved and frees using free_reserved_area().

This is completely unnecessary and the pages allocated with
alloc_pages_exact() can be naturally freed with free_pages_exact().

Replace freeing of memory in fadump_free_buffer() with
free_pages_exact() and simplify allocation code so that it won't mark
allocated pages as reserved.
