crypto: ccp - Fix possible deadlock in SEV init failure path
__sev_platform_init_handle_init_ex_path() calls
rmp_mark_pages_firmware() with locked=false while the parent
function of init_ex_path already acquired the sev_cmd_mutex.
In the case of an RMPUPDATE failure for any page after the first, the cleanup
path would invoke reclaim pages which would result in a deadlock in
sev_do_cmd.
Pass locked=true to honor the lock status of the parent function.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
