[PATCH][next] ACPI: Fix fall-through warning for Clang

["Gustavo A. R. Silva" <gustavoars@kernel.org>]

In preparation to enable -Wimplicit-fallthrough for Clang, fix a
fallthrough warning by simply dropping the empty default case at
the bottom.

This contributes to the ongoing efforts to globally enable
-Wimplicit-fallthrough for Clang.
