P J P b947ac2bf2 e1000: Avoid infinite loop in processing transmit descriptor (CVE-2015-6815) 
While processing transmit descriptors, it could lead to an infinite
loop if 'bytes' was to become zero; Add a check to avoid it.

[The guest can force 'bytes' to 0 by setting the hdr_len and mss
descriptor fields to 0.
