platform/x86: intel-vbtn: Stop calling "VBDL" from notify_handler
commit 84c16d01ff219bc0a5dca5219db6b8b86a6854fb upstream. Commit 14c200b7ca46 ("platform/x86: intel-vbtn: Fix missing tablet-mode-switch events") causes 2 issues on the ThinkPad X1 Tablet Gen2: 1. The ThinkPad will wake up immediately from suspend 2. When put in tablet mode SW_TABLET_MODE reverts to 0 after about 1 second Both these issues are caused by the "VBDL" ACPI method call added at the end of the notify_handler. And it never became entirely clear if this call is even necessary to fix the issue of missing tablet-mode-switch events on the Dell Inspiron 7352. Drop the "VBDL" ACPI method call again to fix the 2 issues this is causing on the ThinkPad X1 Tablet Gen2.
