Describe the bug

An error occurs when trying to boot into the system after suspend if PreserveVideoMemoryAllocations is enabled:

[   10.255125] NVRM: GPU 0000:05:00.0: PreserveVideoMemoryAllocations module parameter is set. System Power Management attempted without driver procfs suspend interface. Please refer to the 'Configuring Power Management Support' section in the driver README.
[   10.255127] nvidia 0000:05:00.0: PM: pci_pm_freeze(): nv_pmops_freeze+0x0/0x20 [nvidia] returns -5

To Reproduce

1. Create a file /etc/modprobe.d/nvidia-power-management.conf with the following content:

options nvidia NVreg_PreserveVideoMemoryAllocations=1 NVreg_TemporaryFilePath=/var/tmp

2. sudo update-initramfs -c -k all to re-generate the kernels.
3. Reboot.
4. Go to suspend mode.
5. Get an error when trying to load a saved state.
