treewide: remove unnecessary invalid range checks in memblock iteration loops

The memblock API guarantees that for_each_mem_range() and
for_each_mem_pfn_range() never return an invalid range, meaning start is
always less than end.

Several memblock callers still have unnecessary invalid range checks in
their loop bodies, so remove them.

[...]

Applied to range-checks branch of memblock.git tree, thanks!
