mm/vmalloc.c: optimize to reduce arguments of alloc_vmap_area()
If called by __get_vm_area_node(), by open coding the field assignments of
'struct vm_struct *vm', and move the vm->flags and vm->caller assignments
into __get_vm_area_node(), the passed in arguments 'flags' and 'caller'
can be removed.
This alleviates overloaded arguments passed in for alloc_vmap_area().
