Subject: [PATCH v2] platform/x86: ideapad-laptop: Fix no_hw_rfkill_list for
 Lenovo RESCUER R720-15IKBN

Commit ae7c8cba3221 ("platform/x86: ideapad-laptop: add lenovo RESCUER 
R720-15IKBN to no_hw_rfkill_list") added
    DMI_MATCH(DMI_BOARD_NAME, "80WW")
for Lenovo RESCUER R720-15IKBN.

But DMI_BOARD_NAME does not match 80WW on Lenovo RESCUER R720-15IKBN, 
thus cause Wireless LAN still be hard blocked.

On Lenovo RESCUER R720-15IKBN:
    ~$ cat /sys/class/dmi/id/sys_vendor 
    LENOVO
    ~$ cat /sys/class/dmi/id/board_name 
    Provence-5R3
    ~$ cat /sys/class/dmi/id/product_name 
    80WW
    ~$ cat /sys/class/dmi/id/product_version 
    Lenovo R720-15IKBN

So on Lenovo RESCUER R720-15IKBN:
    DMI_SYS_VENDOR should match "LENOVO",
    DMI_BOARD_NAME should match "Provence-5R3",
    DMI_PRODUCT_NAME should match "80WW",
    DMI_PRODUCT_VERSION should match "Lenovo R720-15IKBN".

Fix it, and in according with other entries in no_hw_rfkill_list, 
use DMI_PRODUCT_VERSION instead of DMI_BOARD_NAME.

RESCUER R720-15IKBN to no_hw_rfkill_list")
