[PATCH 13/13] resctrl: don't ignore options

[Miklos Szeredi]

The options "sync", "async", "dirsync", "lazytime", "nolazytime", "mand"
and "nomand" make no sense for the resctrl 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().
