mm/damon/vaddr: add 'nr_piece == 1' check in damon_va_evenly_split_region()
As discussed in [1], damon_va_evenly_split_region() is called to
size-evenly split a region into 'nr_pieces' small regions,
when nr_pieces == 1, no actual split is required. Check that case
for better code readability and add a simple kunit testcase.
