restore: fix "Defect type: UNINIT"

Static code analysis reported:

  1. criu/cr-restore.c:2438:2: var_decl: Declaring variable "end_vma"
     without initializer.
  4. criu/cr-restore.c:2451:5: assign: Assigning: "s_vma" = "&end_vma",
     which points to uninitialized data.
  7. criu/cr-restore.c:2449:4: uninit_use: Using uninitialized value
     "s_vma->list.next".

This tries to fix it by initializing the variable.
