Elena Salomatkina ef18243f8e net/sched: cbs: Fix integer overflow in cbs_set_port_rate() 
[ Upstream commit 397006ba5d ]

The subsequent calculation of port_rate = speed * 1000 * BYTES_PER_KBIT,
where the BYTES_PER_KBIT is of type LL, may cause an overflow.
At least when speed = SPEED_20000, the expression to the left of port_rate
will be greater than INT_MAX.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
