This patch depends on a vhm patch merged, "vhm: setup ioreq shared buf
in IC_CREATE_VM ioctl". We intend to combine VM creating and ioreq
shared page setup into one step. For compatibility issue, we need follow
the patch dependency to merge accordingly.
This patch also drops vm_open/vm_close which will be intergrated into
vm_create/vm_destroy.
