swapon: fix discard option parsing

The current code does not work as expected if there is an option
behind the discard=<arg>, for example:

  swapon /dev/sdc -o discard=once,pri=10

ignores "once" the result is SWAP_FLAG_DISCARD; strace:

Old version:

  swapon("/dev/sdc", SWAP_FLAG_PREFER|SWAP_FLAG_DISCARD|10) = 0

Fixed version:

  swapon("/dev/sdc", SWAP_FLAG_PREFER|SWAP_FLAG_DISCARD|SWAP_FLAG_DISCARD_ONCE|10) = 0
