qemu: introduce vmware vga FIFO rewind patch to fix qemu hang

In some circumstance guest driver got interrupted before inserting all args
for one command, so that qemu get an invalid args and hang. GL patch
doesn't consume these missing args, which further cause FIFO disorder.

This commit reverts wrong behavior of GL patch, and introduces a qemu
upstream patch to rewind FIFO unpon detecting incomplete command.

[BUGID #111] fixed by this.
