90c05f68fc net: lwip: ping: set net_try_count to 1
The legacy network stack sets net_try_count to 1 at the beginning of the
net_loop() function. This is required for net_start_again() to work
properly. Therefore, set the variable accordingly in the do_ping()
function when NET_LWIP=y. This fixes an issue where a ping to an
unreachable destination would run twice on the same network device. For
example with qemu_arm64_lwip_defconfig:

 => dhcp
 DHCP client bound to address 10.0.2.15 (3 ms)
 => ping 10.0.0.1
 Using virtio-net#32 device
 ping failed; host 10.0.0.1 is not alive
 Using virtio-net#32 device
 ping failed; host 10.0.0.1 is not alive
 => QEMU: Terminated

8f80e30579 lwip: sntp: remove redundant sys_check_timeouts()
Now that sys_check_timeouts() is called in net_lwip_rx(), there is no
need to call it from the SNTP receive loop. Remove the redundant call.

1361d9f4f0 lwip: dns: do not print IP address when a variable is specified
When calling "dns <hostname> <varname>", do not print out the IP address
of <hostname> onto the console. Print it only when no variable is
passed. The reason is to be able to call do_dns() from another command
in need of the DNS services without polluting the output.

d3136d22a6 lwip: dns: do not return CMD_RET_FAILURE on successful resolution
The DNS loop checks for a non-zero IP address after DNS resolution, but
the address is in fact never copied into the context. Fix that.
