[PATCH] drm/amdgpu: Fix an error handling path in amdgpu_device_xgmi_reset_func()

[Christophe JAILLET]

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.

Compile tested only.

This patch is completely speculative, review with care!

It is only based on naming where an _enter() function if not followed by an
_exit() in some paths but is in other paths.
