arv_gc_feature_node_get_actual_access_mode returns unexpected ARV_GC_ACCESS_MODE_RO

[TIS-Edgar]

Hi Emmanuel,

Describe the bug

arv_gc_feature_node_get_actual_access_mode returns ARV_GC_ACCESS_MODE_RO
for free-floating Integer nodes, whereas ARV_GC_ACCESS_MODE_RW is expected.

To Reproduce

A small c program that reproduces the problem can be found here,
as well as the corresponding genicam description:

Expected behavior

The node should have RW access mode.

Camera description:

Seems to be reproducible with all TIS cameras. GigE and USB3.
Verified with DMK 33UX273, DFK 33GP1300 and DFK 33GP1300.

Platform description:

• current master (08dc0ba)
• OS: Debian Testing
• Hardware: amd64

This seems to be fixable by having arvgcfeaturenode.c@522:_get_access_mode return ARV_GC_ACCESS_MODE_RW.

As always, thank you in advance!
