Fixes the following from checkpatch.pl:
WARNING: Use of volatile is usually wrong: see
Documentation/process/volatile-considered-harmful.rst
+ volatile uint32_t *wb;
WARNING: Use of volatile is usually wrong: see
Documentation/process/volatile-considered-harmful.rst
+ volatile uint32_t *ptr;
'wb' field from 'amdgpu_wb' struct & 'ptr' field from
'amdgpu_mem_scratch', is not used to access h/w directly, neither they
are shared variables, so volatile is not necessary
