[src/trunk]: src/sbin/swapctl don't stop processing /etc/fstab when one entry...

[mrg <mrg%NetBSD.org@localhost>]

details:   https://anonhg.NetBSD.org/src/rev/98799c9bc645
branches:  trunk
changeset: 811081:98799c9bc645

description:
don't stop processing /etc/fstab when one entry fails, both for
add and remove loops.  now when you add a new swap file and run
"swapctl -A" it won't give up after the existing one gives EBUSY
and move on to the rest.
