[PATCH] platform/x86: hp-wmi: Actually use mask parameter in hp_wmi_hw_state

["Michel Dänzer" <michel@daenzer.net>]

We were always checking bit 0 (which represents the docked state)
regardless of the mask.

Fixes the "tablet mode" state always being reported the same as the
docked state, which with current libinput can cause the built-in input
devices of laptops to be incorrectly disabled while docked.

Fixes: ("platform/x86: hp-wmi: Refactor dock and tablet state fetchers")
