x86/speculation: Add cpu_show_gds() prototype

Browse source

commit a57c27c7ad upstream.

The newly added function has two definitions but no prototypes:

drivers/base/cpu.c:605:16: error: no previous prototype for 'cpu_show_gds' [-Werror=missing-prototypes]

Add a declaration next to the other ones for this file to avoid the
warning.
