percpu: make @dyn_size always mean min dyn_size in first chunk init functions
In pcpu_build_alloc_info() and pcpu_embed_first_chunk(), @dyn_size was ssize_t, -1 meant auto-size, 0 forced 0 and positive meant minimum size. There's no use case for forcing 0 and the upcoming early alloc support always requires non-zero dynamic size. Make @dyn_size always mean minimum dyn_size. While at it, make pcpu_build_alloc_info() static which doesn't have any external caller as suggested by David Rientjes.
