Description
To reproduce:
1. Setup a remote device that needs VPN connection (10.9.78.65)
2. Turn off the VPN
3. Start Creator, open settings, switch to Devices page - the main thread freezes for about 10 seconds.
The regression was introduces in: https://codereview.qt-project.org/c/qt-creator/qt-creator/+/457117.
Creator 9 does not suffer from this issue.

In addition, when GDB server executable field is set to: ssh://berlin@10.9.78.65/., the freeze takes longer (30 seconds) and the following asserts appear:
SOFT ASSERT [08:42:54.750]: "state() == QProcess::Running" in /home/jarek/dev/creator-11/src/libs/utils/process.cpp:1564 qtc.utils.deviceshell: Timeout while trying to check for "cat" SOFT ASSERT [08:42:54.750]: "m_shell" in /home/jarek/dev/creator-11/src/plugins/remotelinux/linuxdevice.cpp:850 SOFT ASSERT [08:42:54.750]: "m_shell" in /home/jarek/dev/creator-11/src/plugins/remotelinux/linuxdevice.cpp:850
