Add "Permission denied" error handling for Extreme Exos

[Thorbijoern]

SUMMARY

I stumbled over an error with the scp2 command on a 5320 model switch with EXOS Version 31.x

Couldn't open local file \"/scratch/summit_arm-32.4.1.10.xos\" for writing: Permission denied

Ansible/the exos modules don't recognize it as error and pretend it's fine. So i just want to add it in case somebody else has a similar problem and it might help.

• Bugfix Pull Request

COMPONENT NAME

exos

ADDITIONAL INFORMATION

It only happens on a switch that is freshly unconfigured. It's probably a bug, but i use download image for now. I don't know the exact Exos version anymore, i would have to downgrade the switch and test a bit.

@Thorbijoern that's OK, thanks for adding the fragment and for the bugfix!
Just a fyi, this is the only merged PR since the previous release, so I wouldn't expect the fix to be available in the package soon: I would wait for a bit more fixes/new features to release them at once.
