Probably something like this:

map $host $username {
  some.domain.com usera;
  another.one.net userb;
}

server {
  root /srv/www/users/$username/wp;
  access_log /var/log/nginx/vhosts/$username.access.log;
  ...
}

Or this (without map):

server {
  server_name ~^(?<username>.+)\.domain\.com$;
  root /srv/www/users/$username/wp;
  ...
}
