Alan Cox ba67369628 Recursion on the free page queue mutex occurred when UMA needed to allocate 
a new page of radix trie nodes to complete a vm_radix_insert() operation
that was requested by vm_page_cache().  Specifically, vm_page_cache()
already held the free page queue lock when UMA tried to acquire it through
a call to vm_page_alloc().  This code path no longer exists, so there is no
longer any reason to allow recursion on the free page queue mutex.

Improve nearby comments.
