Refactor the currdev setting to find the device we booted from. Limit searching when we don't already have a reasonable currdev from that to the same device only. Search a little harder for ZFS volumes as that's needed for loader.efi to live on an ESP. Sponsored by: Netflix Differential Review: https://reviews.freebsd.org/D13784
