drm/radeon/trinity_dpm: fix a memleak in trinity_parse_power_table

Browse Source 
[ Upstream commit 28c28d7f77c06ac2c0b8f9c82bc04eba22912b3b ]

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.
