[Libva] [PATCH][libva-intel-driver] i965_GetDisplayAttributes: propagate flags from src to dst

[Daniel Charles]

flags need to be propagated for user to know which flags
are supported by VADisplayAttribType.

When only VA_DISPLAY_ATTRIB_SETTABLE is reported as flag
then it has to be propagated back to user.  The rest of the
values should be left untouched
