------------------

[ Upstream commit 4d9b2864a415fec39150bc13efc730c7eb88711e ]

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.
