Enric Balletbo i Serra 23a70bf9c3 net/net.c: Update ipaddr if the environment has changed 
At least on ARM the ipaddr is only set in board_init_r function. The
problem is if ipaddr is not defined in environment importing another
environment defined don't update the ipaddr value.

For example, suppose we've a default environment without net variables
defined and we want to import an uEnv.txt environment from SD-card like
this:

  ipaddr=192.168.2.240
  netmask=255.255.255.0
  gatewayip=192.168.2.1
  serverip=192.168.2.114

Then if you try boot from NFS results in:

  Importing environment from mmc ...
  Running uenvcmd ...
  smc911x: detected LAN9221 controller
  smc911x: phy initialized
  smc911x: MAC ac🇩🇪48:00:00:00
  *** ERROR: `ipaddr' not set

The ipaddr at this point is NULL beacause is only set at board_init_r
function. This patch updates the ipaddr value if the environment has
changed.
