Remove nonsensical vm_map_{clear,set}_recursive() calls

Browse Source 
from vm_map_pageable().  At the point they called, vm_map_pageable()
holds a read (or shared) lock on the map.  The purpose
of vm_map_{clear,set}_recursive() is to disable/enable repeated
write (or exclusive) lock requests by the same process.
