swapon: (man) fix --priority description

It's not true anymore that Linux uses -1 as the default. I could be
also another negative number (default is -2 for the first swap since
kernel commit a2468cc9bfdff6139f59ca896671e5819ff5f94a).

-Specify the priority of the swap device. _priority_ is a value between -1 and 32767. Higher numbers indicate higher priority. See *swapon*(2) for a full description of swap priorities. Add **pri=**__value__ to the option field of _/etc/fstab_ for use with *swapon -a*. When no priority is defined, it defaults to -1.
