Subject: nvdimm: Remove empty if statement
Git-commit: 19418b024427ec60ba6084addf691a8d93670398
Patch-mainline: v4.20-rc1
References: bsc#1111921, bsc#1113408, FATE#326765, bsc#1113972

This patch removes an empty statement from an if expression and promotes
the else statement to the if expression with the expression logic reversed.

I feel this is more readable as the empty statement can lead to issues if
any additional logic was ever added.
