Subject: [PATCH] virtio/console: Allocate scatterlist according to the current
 pipe size

Allocate scatterlist according to the current pipe size.
This allows splicing bigger buffer if the pipe size has
been changed by fcntl.

Changes in v2:
 - Just a minor fix for avoiding a confliction with previous patch.
