Thomas Munro 483520eca4 Tolerate ENOSYS failure from sync_file_range(). ... One unintended consequence of commit 9ccdd7f6 was that Windows WSL users started getting a panic whenever we tried to initiate data flushing with sync_file_range(), because WSL does not implement that system call. Previously, they got a stream of periodic warnings, which was also undesirable but at least ignorable. Prevent the panic by handling ENOSYS specially and skipping the panic promotion with data_sync_elevel(). Also suppress future attempts after the first such failure so that the pre-existing problem of noisy warnings is improved. Back-patch to 9.6 (older branches were not affected in this way by 9ccdd7f6).
