net: update the register_netdevice() kdoc 

The BUGS section looks quite dated, the registration
is under rtnl lock. Remove some obvious information
while at it.

/**
* register_netdevice - register a network device
* @dev: device to register
* register_netdevice() - register a network device
* @dev: device to register
*
* Take a completed network device structure and add it to the kernel
* interfaces. A %NETDEV_REGISTER message is sent to the netdev notifier
* chain. 0 is returned on success. A negative errno code is returned
* on a failure to set up the device, or if the name is a duplicate.
*
* Callers must hold the rtnl semaphore. You may want
* register_netdev() instead of this.
*
* BUGS:
* The locking appears insufficient to guarantee two parallel registers
* will not get the same name.
* Take a prepared network device structure and make it externally accessible.
* A %NETDEV_REGISTER message is sent to the netdev notifier chain.
* Callers must hold the rtnl lock - you may want register_netdev()
* instead of this.
