David Rientjes e74bd96989 x86/boot: Fix memory leak in default_get_smp_config() 
When default_get_smp_config() is called with early == 1 and mpf->feature1
is non-zero, mpf is leaked because the return path does not do
early_memunmap().

Fix this and share a common exit routine.

Fixes: 5997efb967 ("x86/boot: Use memremap() to map the MPF and MPC data")
