Eliminate artificial increasing of 'netdev_opens' counter in loader's net_open().

This was introduced as a workaround long time ago for some Alpha firmware
(which is now gone), and actually prevented net_close() to ever be
called.

Certain firmwares (U-Boot) need local shutdown operations to be performed on a
network controller upon transaction end: such platform-specific hooks are
supposed to be called via netif_close() (from within net_close()).

This change effectively reverts the following CVS commit:

    sys/boot/common/dev_net.c

    revision 1.7
    date: 2000/05/13 15:40:46;  author: dfr;  state: Exp;  lines: +2 -1
    Only probe network settings on the first open of the network device.
    The alpha firmware takes a seriously long time to open the network device
    the first time.

Also suppress excessive output while netbooting via loader, unless debugging.

While there, make sys/boot/uboot more style(9) compliant.
