Description:
fsync() return errno doesn't in (ENOLCK, EIO, EINTR), leads to assertion failed.
No errno print in error log, making it hard to diagnose what type of system error occurs.

How to repeat:
No errno print, don't have more detailed info.

Suggested fix:
add a `ib::error() << strerror(errno)` string before ut_error.
