qcacld-3.0: Remove struct vdev_create_req_param

The following patch removed all usage of struct vdev_create_req_param:
  qcacld-3.0: Send the vdev create to firmware in the caller thread
  Change-Id Iafb186b13d948e421d152c3142cb8614fdbbffa6

However it didn't remove the actual struct, so remove it now.

Change-Id: I20937b00ecdc61f7b349dd287092d5ebd6d7e9c4
CRs-Fixed: 3424785
