selftests/mm: use long for dwRegionSize

Browse source 
Change the type of 'dwRegionSize' in wp_init() and wp_free() from int to
long to match callers that pass long or unsigned long long values.

wp_addr_range function is left unchanged because it passes 'dwRegionSize'
parameter directly to pagemap_ioctl, which expects an int.

This patch does not fix any actual known issues.  It aligns parameter
types with their actual usage and avoids any potential future issues.
