Alan Cox 9fc4739d2a In general, we call pmap_remove_all() before calling vm_page_cache(). So, ...

the call to pmap_remove_all() within vm_page_cache() is usually redundant.
This change eliminates that call to pmap_remove_all() and introduces a
call to pmap_remove_all() before vm_page_cache() in the one place where
it didn't already exist.

When iterating over a paging queue, if the object containing the current
page has a zero reference count, then the page can't have any managed
mappings.  So, a call to pmap_remove_all() is pointless.

Change a panic() call in vm_page_cache() to a KASSERT().
