cpu/x86/smm: Fix smm_get_save_state() returning invalid pointer

The smm_get_save_state() function returns an invalid pointer (negative
pointer) when the cpu variable is equal to the number of CPUs. This
leads to a hang when the pointer is used to access the save state.

TEST=No unexpected hangs in System Management Mode (SMM) were detected
     on fatcat.
