Fixing a bug in team driver due to incorrect 'unsigned int' to 'int' conversion
Roundrobin runner of team driver uses 'unsigned int' variable to count
the number of sent_packets. Later it is passed to a subroutine
team_num_to_port_index(struct team *team, int num) as 'num' and when
we reach MAXINT (2**31-1), 'num' becomes negative.
This leads to using incorrect hash-bucket for port lookup
and as a result, packets are dropped. The fix consists of changing
'int num' to 'unsigned int num'. Testing of a fixed kernel shows that
there is no packet drop anymore.
