Konstantin Khlebnikov 3c06c178cf sched/rt: Check integer overflow at usec to nsec conversion 
[ Upstream commit 1a010e29cfa00fee2888fd2fd4983f848cbafb58 ]

Example of unhandled overflows:

 # echo 18446744073709651 > cpu.rt_runtime_us
 # cat cpu.rt_runtime_us
 99

 # echo 18446744073709900 > cpu.rt_period_us
 # cat cpu.rt_period_us
 348

After this patch they will fail with -EINVAL.
