amdgpu: remove unreachable code 



In the function amdgpu_uvd_cs_msg(), every branch in the switch
statement will have a return, so the code below the switch statement
will not be executed.

Eliminate the follow smatch warning:

drivers/gpu/drm/amd/amdgpu/amdgpu_uvd.c:845 amdgpu_uvd_cs_msg() warn:
ignoring unreachable code.
