[PKT_SCHED]: Move tc_u32_mark into pkt_cls.h

The tc_u32_mark structure is used as part of the netlink message
from the user API to the kernel, so it needs to be moved to
include/linux/pkt_cls.h and have types changed from u32 to __u32.

Also, the definition of u32 performance counters doesn't need to depend
on the config option.  The definition can exist even if the code isn't
enabled.
