ply-device-manager: Add != 0 to strcmp calls

strcmp is kind of a confusing function in that it returns
non-zero when the strings are not equal. That is
especially counterintuitive when this non-zero value is
treated as a TRUE boolean.

This commit just adds some != 0's to a couple of strcmp
calls for clarity.
