drm/radeon/dpm: fix a memleak in sumo_parse_power_table

[ Upstream commit 0737df9ed0997f5b8addd6e2b9699a8c6edba2e4 ]

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.
