Fix clib_bitmap_next_clear() function when no clear bits left
If the bitmap has no bit clear after the input bit position i, the function will return i even if its bit is set. Fix is to return the next bit just beyond the free bitmap. This can cause IP neighbor scan crash in ip_neighbor_scan() with a debug image. With production image, ip_neighbor_scan() may still function, AFAICT, with extra neighbor delete attempts for entries already deleted, until these entries are reused for new neighbors.
