Subject: [PATCH v2 4/4] 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.
