Subject: x86/bugs: Fix __ssb_select_mitigation() return type
Git-commit: d66d8ff3d21667b41eddbe86b35ab411e40d8c5f
Patch-mainline: v4.17-rc7
References: bsc#1087082 CVE-2018-3639

__ssb_select_mitigation() returns one of the members of enum ssb_mitigation,
not ssb_mitigation_cmd; fix the prototype to reflect that.

Fixes: 24f7fc83b9204 ("x86/bugs: Provide boot parameters for the spec_store_bypass_disable mitigation")
