[PATCH] drm/amdgpu: initialize amdgpu_ras_query_error_count() error count parameters

[trix at redhat.com]

From: Tom Rix <trix at redhat.com>

Static analysis reports this problem
amdgpu_ras.c:2324:2: warning: 2nd function call argument is an
  uninitialized value
        atomic_set(&con->ras_ce_count, ce_count);
        ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

ce_count is normally set by the earlier call to
amdgpu_ras_query_error_count().  But amdgpu_ras_query_error_count()
can return early without setting, leaving its error count parameters
in a garbage state.

Initialize the error count parameters earlier.
