[PATCH v1 03/15] ACPI: button: Improve warning message regarding lid state

["Rafael J. Wysocki" <rafael@kernel.org>]

From: "Rafael J. Wysocki" <rafael.j.wysocki@intel.com>

The warning message regarding an unexpected lid state printed by
acpi_lid_notify_state() is quite cryptic and there is no information
in it to indicate that it is about a platform firmware defect.  In
fact, it can only be understood after reading the comment below the
statement printing it.

For this reason, replace it with a more direct one including FW_BUG so
its connection to a firmware issue is clearer.

While at it, fix up a comment preceding the statement printing the
message in question.
