Konstantin Belousov 7a432b84e8 Fix two similar bugs in the populate vm_fault() code. ... If pager' populate method succeeded, but other thread raced with us and modified vm_map, we must unbusy all pages busied by the pager, before we retry the whole fault handling. If pager instantiated more pages than fit into the current map entry, we must unbusy the pages which are clipped. Also do some refactoring, clarify comments and use more clear local variable names.
