[U-Boot] [PATCHv2] sntp: avoid use of uninitialized variable

[Chris Packham]

From: Luuk Paulussen <luuk.paulussen at alliedtelesis.co.nz>

When we use the ntpserverip environment variable argv[1] may not be set.
Printing the error message using the NetNtpServerIP variable ensures the
correct output in both cases.
