This patch modifies the gdm72xx driver to properly release a netlink
socket using netlink_kernel_release. It fixes the following kernel
crash, which occurs after repeatedly suspending and resuming a system.

gdm72xx uses networking interfaces, so it should depend

...
This patch uses SET_NETDEV_DEV to set up a 'device' parent link in sysfs
(e.g. /sys/class/net/wm0/device) for a gdm72xx device.

staging: gdm72xx: WIMAX_GDM72XX_USB_PM should depend on USB_SUSPEND
...
Use Kconfig logic instead of a rude #error in the driver source,
which breaks m68k-allmodconfig.
Also remove the "default n", as that's the default.
