lagg(4): release LAGG_LOCK before mtu changing
PR kern/57650

Make the lagg interface up before change its MTU
This change is related to PR kern/57650

Fix missing IFNET_LOCK holding while destroy the lagg interface
copy MTU of lagg to a interface added to lagg
even if the interface is the first member of the lagg

This change breaks ATF test case for lagg MTU

Update the test case for MTU of lag to adapt new behavior

Update lagg(4) manual
1. corrected the wrong example
   - lagg(4) can not add multiple port and set its priority at once
      - This is the restriction of ifconfig(8)
2. adapted to changed behavior related to MTU
   - Changed not to copy MTU of the 1st physical interface
     to lagg(4) to prevent locking against myself
