Subject: i386 kern: fix overflow in vm_object_print_part call

The call to vm_object_print_part was passing 0ULL and ~0ULL
for offset and size, respectively. These values are 64-bit
(unsigned long long), which causes compiler warnings when
building for 32-bit platforms where vm_offset_t and vm_size_t
are typedefs of uintptr_t (i.e., unsigned int).

This patch replaces those constants with 0 and UINTPTR_MAX,
which match the expected types and avoid implicit conversion
or overflow warnings.

No functional change.
