Change watchdog timeout logging from INFO to ERROR. (#50455)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/50455
Certain systems only print logging messages for ERROR/WARN and the
error message that the watchdog is timing out a particular operation is pretty
important.
As a result, changing its level to ERROR instead of INFO.
