System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: GeForce GTX 1080/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 456.71

Blender Version
Broken: version: 3.0.0 Alpha, branch: master (modified), commit date: 2021-06-23 04:56, hash: 071799d4fc
Worked: 2.93.0

Short description of error
Geometry nodes crash when two nodes that are connected to a reroute and feed into "Join Geometry" are both muted.

Exact steps for others to reproduce the error

Make a default geometry node tree.
Add a "Join Geometry" node.
Add two arbitrary input nodes (i used "Assign Material").
Connect both input nodes to a "Reroute" node.
Feed some source geometry into the Reroute node.
Mute both nodes feeding into the Join Geometry
Geometry nodes assert fails, because the Join Geometry node has not computed any output geometry.

Can confirm this in the 3.0.0 alpha. I get an assert failure in the debug build:

BLI_assert failed: D:\blender-git\blender\source\blender\modifiers\intern\MOD_nodes_evaluator.cc:941, assert_expected_outputs_have_been_computed(), at 'output_state.has_been_computed'

Stacktrace: P2205

No crash in 2.93.0
