sysfs IO enhancements
Add retries for some sysfs IO errors:
EIO: Tolerate intermittant device or bus failures.
ETIMEDOUT: Tolerate intermittant timeouts.
EAGAIN: Tolerate drivers that do not block.
ENXIO: Tolerate momentarily unplugged devices on busses that don't
support hotplug.
EBADMSG: Tolerate CRC errors.
Flush stdio buffers after writes.
Remove redundant retry and delay constants.
Resolves: openbmc/openbmc#2262
