[GBM] Allow ForceLinear buffers even when DRM_FORMAT_MOD_LINEAR is not in
the modifier list
https://bugs.webkit.org/show_bug.cgi?id=309351
Reviewed by Carlos Garcia Campos.
When ForceLinear is requested but DRM_FORMAT_MOD_LINEAR is not among the
supported modifiers, clear the modifier list instead of skipping the format
entirely. This allows GBM to allocate a linear buffer via the implicit
modifier path. Also simplify the error check to crash on any negotiation
failure rather than only on the ForceLinear case.
Covered by existing tests - when using certain GPU drivers.
