	Reviewers accepted v2 of the patch, but what got committed was v1, with the R-bys for v2. This is the v1->v2 followup fix.

2014-02-25	qemu_file: use fwrite() correctly	Juan Quintela
	fwrite() returns the number of items written. But when there is one error, it can return a short write. In the particular bug that I was tracking, I did a migration to a read-only filesystem. And it was able to finish the migration correctly. fwrite() never returned a negative error code, nor zero, always 4096. (migration writes chunks of about 14000 bytes). And it was able to "complete" the migration with success (yes, reading the file was a bit more difficult). To add insult to injury, if your amount of memory was big enough (12GB on my case), it overwrote some important structure, and from them, malloc failed. This check makes the problem go away.
