[BUG] WALinuxAgent is not able to copy ovf-env.xml

waagent reports the failed provision state on VM and therefore I can't backup the VM

**Distro and WALinuxAgent details (please complete the following information):**
- Distro and Version: CentOS Linux release 7.9.2009
- Kernel Version: 6.0.8-1.el7
- WALinuxAgent version: WALinuxAgent-2.2.46

**Additional context**
I am not using cloud-init, I tried to work this around by reading the following issue: https://github.com/Azure/WALinuxAgent/issues/2058
But unfortunately in my case the device isn't mounted at all so the solutions didn't workout for me
