The dhcp command is supposed to have the following syntax as per "help dhcp":

dhcp [loadAddress] [[hostIPaddr:]bootfilename]

In other words, any arguments should be passed to an implicit tftpboot command after the DHCP exchange has occurred.

Add the missing code to the lwIP version of do_dhcp().
