[PATCH v1 1/2] kho: remove useless phys increment in inner loop

[Chenghao Duan]

The statement phys += contig_pages * PAGE_SIZE at the end of the inner
for-loop in kho_restore_vmalloc() is redundant code. The variable 'phys'
is local to each loop iteration (re-assigned from chunk->phys[i] on every
iteration) and is never referenced after this increment, so the statement
has no functional impact. Remove it to avoid confusion during code review.
