rpc_pkt.u.call.data is an array of uint32_t. There is no need to convert
it to uint32_t *.
memcpy() expects void * as it 1st and 2nd argument. There is no point in
converting pointers to char * before passing them to memcpy().
In ntohl(data[1]) != 0 calling ntohl() is superfluous. If the value is
zero, does not depend on the byte order.

If NFSv2 and NFSv3 are not available, print an error message since NFSv4 is not supported.
Tested on iMX6 sabrelite with 4 Linux NFS servers:
* NFSv2 + NFSv3 + NFSv4 server: use NFSv2 protocol
* NFSv2 + NFSv3 server: use NFSv2 protocol
* NFSv3 + NFSv4 server: use NFSv3 protocol

This patch tackles the time out problem which leads to break the
boot process, when loading file over nfs. The patch does two things.
First of all, we just ignore messages that arrive with a rpc_id smaller
then the client id. We just interpret this messages as answers to
formaly timed out messages.
Second, when a time out occurs we double the time to wait, so that we
do not stress the server resending the last message.

- NfsTimeout() does not correctly update the NFS timeout value which
results in NfsTimeout() only being called once in certain situations.
This can result in the 'nfs' command hanging indefinetly. For
example, the command:
nfs 192.168.0.1:/home/user/file
will not exit until ctrl-c is pressed if 192.168.0.1 does not have an
NFS server running.
This issue is resolved by reinitializting the NFS timeout value inside
NfsTimeout() when a timeout occurs.
- Make the 'nfs' command print the 'T' character when a timeout occurs.
Previously there was no indication that timeouts were occuring.
- Mimic the 'tftpboot' command and when a download fails print "Retry
count exceeded; starting again", and restart the download taking the
'netretry' environment variable into account.
