mm/memblock: Remove redundant pageblock_align() in free_unused_memmap()

Browse Source 
The assignment `prev_end = pageblock_align(end)` is redundant because
`prev_end` was already aligned to pageblock oundaries inside the loop.
Since pageblock_align() is a pure function, calling it again with the
same input produces the same result.

This line was added in commit f921f53e08 ("memblock: align freed
memory map on pageblock boundaries with SPARSEMEM"). Remove it to
simplify the code.
