For the NVMe device given, sends the WDC vendor unique pfail crash dump
request and saves the result to file. In current implementation pfail crash
dump is captured if it is present. On success it will save the dump in file
with appropriate suffix. Note that this command will clear the available
dump from the device on success.
The <device> parameter is mandatory NVMe character device (ex: /dev/nvme0).
This will only work on WDC devices supporting this feature.
Results for any other device are undefined.
