            Bug ID: 51238
           Summary: regression: World of Warships fails with
                    wined3d_deferred_context_*  functions available.
           Product: Wine
           Version: 6.10

hack removing deferred context support

Since wine6.10, World of Warships crashes with a dialog box
"""
A critical error has occurred
The error information was collected to the Reports folder
Use the link below for support
[Restart] [Terminate]
"""
upon game start (on the black screen, before displaying the WoWS logo). The
Report data suggests "crash_type": "unhandled_exception" "code_of_exception":
3221225477.

Bisecting points to 60027fcc23e665fdd073e5fbe33bdd4850cd9e84, which doesn't
revert cleanly. But simply removing the wined3d_deferred_context_* functions
(see attached patch/hack) allows WoWS to work normally again.

Diffing the WINEDEBUG=trace+d3dx logs shows they diverge after the line
"fixme:d3d11:d3d11_device_CheckFeatureSupport Returning fake threading support
data."
The stock version prints a few variations of 
"fixme:d3d:wined3d_deferred_context_update_sub_resource context 0x262ef030,
resource 0x23ccc360, sub_resource_idx 0, box (0, 0, 0)-(20, 20, 1), data
0x1bd92000, row_pitch 80, slice_pitch 1600, stub!"
, and then goes on to spam the _Locinfo__Locinfo_ctor_cat_cstr FIXME (possibly
while building the dialog box). The hacked version instead spams complaints
about
"err:d3d:state_undefined Undefined state UNKNOWN_STATE(0) (0)."
, but continues working until I kill the window when the logo is rendered.

Everything above was tested on git revision
aadcff491fc9d823a90cee567c8e1d55cd9a589b in a prefix with winetricks corefonts
vcrun2013 win10.
