drivers: ixgbevf: fix unsigned underflow
'count' is unsigned. It is initialized to zero, then it can be increased
multiple times, and finally it is used in such a way:
>>>> count--;
|
| /* clear timestamp and dma mappings for remaining portion of packet */
| while (count >= 0) {
| count--;
| ...
^
If count is zero here (so, it was never increased), we would have a very
long loop :)
