drm/amd/pm: Avoid open-coded use of ratelimit_state structure's internals
The amdgpu_set_thermal_throttling_logging() function directly accesses
the ratelimit_state structure's ->missed field, which works, but which
also makes it more difficult to change this field. Therefore, make use
of the ratelimit_state_reset_interval() function instead of directly
accessing the ->missed field.
Nevertheless, open-coded use of ->burst and ->interval is still permitted,
for example, for runtime sysfs adjustment of these fields.
