Initialize prev_tsc to cur_tsc. This avoids running the TX queue drain
in the first iteration of the packet processing loop.

Is it really a fix? What was broken?
Isn't it an optimization?

It could be considered an optimization since effectively it prevents entering the if statement on the
first iteration of the loop. I will remove the "fixes" line and reword the subject line.

Fixes: af75078fece3 ("first public release")

If it's really a fix, we should probably backport it, so
Cc: stable@dpdk.org

[Kathleen Capella] 
It is not really a significant problem to be fixed in previous releases so it does not need to be backported.
