Subject: [PATCH] vhost-scsi: Depend on NET for memcpy_fromiovec

scsi.c includes vhost.c which uses memcpy_fromiovec.

This patch fixes this build failure.

   From Randy Dunlap:
   '''
   on x86_64:

   ERROR: "memcpy_fromiovec" [drivers/vhost/vhost_scsi.ko] undefined!

   It needs to depend on NET since net/core/ provides that function.
