Seek to file offset 0 after reading error file
For a fd watching for data in sysfs file, a poll would return
immediately after read unless file is closed and re-opened OR
stream is seeked to 0. This commit chooses latter.
From stackoverflow:
Once poll/select indicates that the value has changed, you need to close and
re-open the file, or seek to 0 and read again.
Also, use EPOLLPRI | EPOLLERR than EPOLLIN as needed by sysfs_inotify
