sched: debug: Promote atomic64_read to u64 for printing

From: Fabio Estevam <[email protected]>

commit 2d58000fd (sched: Fix print format for u64) introduced the following build warning for x86_64:

kernel/sched/debug.c: In function 'print_cfs_rq':
kernel/sched/debug.c:225:2: warning: format '%llu' expects argument of type 'long long unsigned int', but argument 4 has type 'long int' [-Wformat] kernel/sched/debug.c:225:2: warning: format '%llu' expects argument of type 'long long unsigned int', but argument 3 has type 'long int' [-Wformat]

atomi64_read() function may have a different returning type depending on the architecture, so in order to guarantee that it builds fine on any system without warnings, promote it to u64 for printing purpose.
