The options "sync", "async", "dirsync", "lazytime", "nolazytime", "mand"
and "nomand" make no sense for the sysfs filesystem. If these options are
supplied to fsconfig(FSCONFIG_SET_FLAG), then return -EINVAL instead of
silently ignoring the option.
Any implementation, such as mount(8) that needs to parse this option
without failing should simply ignore the return value from fsconfig().
