    _______________________________________________________

Details:

Calling sntp_stop doesn't cancel sntp_try_next_server timeout.
This makes system leak timers, causing it to eventually fail with assert:

Assertion "sys_timeout: timeout != NULL, pool MEMP_SYS_TIMEOUT is empty"
failed at line 212 in lwip/src/core/timeouts.c

Patch attached.
