TFTPROOT loads the RAMdisk through TFTP at boot time. It needs the
network to be functionnal, and therefore must be called after
config_finalize(). Unfortunately, config_finalize() attaches md0
through mdattach(), and when tftproot_getfile() attempts to attach it
later by calling mdattach() again, it gets a failure.
This change checks for the RAMdisk size in mdattach(). If it is zero, then
the RAMdisk has not been loaded yet, and nothing is done. It will be
attached later when tftproot_getfile() will call mdattach()
