drm/amd/pm: Fix an error handling path in vega10_enable_se_edc_force_stall_config()

Commit Message

Christophe JAILLET Nov. 19, 2024, 8:23 p.m. UTC

In case of error after a amdgpu_gfx_rlc_enter_safe_mode() call, it is not
balanced by a corresponding amdgpu_gfx_rlc_exit_safe_mode() call.

Add the missing call.

Fixes: 9b7b8154cdb8 ("drm/amd/powerplay: added didt support for vega10")

*Not* even compile tested only because of missing "hwmgr.h". I've not
checked on which arch it is supposed to run in order to cross-compile.

This patch is speculative, review with care!
