Documentation/watchdog: check return value for magic close
A recent commit added a write to the watchdog test code for doing the "magic
close", but that caused a compile-time warning:
Documentation/watchdog/src/watchdog-test.c: In function ‘main’:
Documentation/watchdog/src/watchdog-test.c:94:5: warning: ignoring return value of ‘write’, declared with attribute warn_unused_result [-Wunused-result]
This changes the code to print a runtime warning if the write fails.
Fixes: 5a2d3de19602 ("Documentation/watchdog: add support for magic close to watchdog-test")
