hwmon: VRM is not written to registers
What was true of reading the VRM value is also true of writing it: not being a register value, it doesn't need hardware access, so we don't need a reference to the i2c client. This allows for a minor code cleanup. As gcc appears to be smart enough to simplify the generated code by itself, this cleanup only affects the source code, the generated binaries are unchanged.
