[PATCH] drm/radeon/dpm: fix a memleak in sumo_parse_power_table

[Zhipeng Lu]

The rdev->pm.dpm.ps allocated by kcalloc should be freed in every
following error-handling path. However, in the error-handling of
rdev->pm.power_state[i].clock_info the rdev->pm.dpm.ps is not freed,
resulting in a memleak in this function.
