KVM: SVM: Add missing member in SNP_LAUNCH_START command structure

The sev_data_snp_launch_start structure should include a 4-byte
desired_tsc_khz field before the gosvw field, which was missed in the
initial implementation. As a result, the structure is 4 bytes shorter than
expected by the firmware, causing the gosvw field to start 4 bytes early.
Fix this by adding the missing 4-byte member for the desired TSC frequency.
