    recv(2): update description of MSG_WAITALL
    
    Remove a note about "data of a different type".  This was a bug that was
    fixed in FreeBSD 15.  Instead put an exact quote from SUS that lists
    allowed cases of a short read with MSG_WAITALL.  See discussion in D57511.
    
    (cherry picked from commit e5bcf988398924568015202bf853b3a9abd3845e)
