kib 3b71d845e6 In vm_fault_copy_entry(), we should not assert that entry is charged
if the dst_object is not of swap type.

It can only happen when entry does not require copy, otherwise
vm_map_protect() already adds the charge. So the assert was right for
the case where swap object was allocated in the vm_fault_copy_entry(),
but not when it was just copied from src_entry and its type is not
swap.

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
