drm/amdgpu: fix amdgpu trace event print string format error

the trace event print string format error.
(use integer type to handle string)

before:
amdgpu_test_kev-1556  [002]   138.508781: amdgpu_cs_ioctl:
sched_job=8, timeline=gfx_0.0.0, context=177, seqno=1,
ring_name=ffff94d01c207bf0, num_ibs=2

after:
amdgpu_test_kev-1506  [004]   370.703783: amdgpu_cs_ioctl:
sched_job=12, timeline=gfx_0.0.0, context=234, seqno=2,
ring_name=gfx_0.0.0, num_ibs=1

change trace event list:
1.amdgpu_cs_ioctl
2.amdgpu_sched_run_job
3.amdgpu_ib_pipe_sync
