x86/sev: Drop unnecessary parameter in snp_issue_guest_request()

Commit

  3e385c0d6ce8 ("virt: sev-guest: Move SNP Guest Request data pages handling under snp_cmd_mutex")

moved @input from snp_msg_desc to snp_guest_req which is passed to
snp_issue_guest_request().

Drop the extra parameter.

No functional change intended.
