fs: create __sb_write_started() helper

Browse source

Similar to sb_write_started() for use by other sb freeze levels.

Unlike the boolean sb_write_started(), this helper returns a tristate
to distiguish the cases of lockdep disabled or unknown lock state.

This is needed for fanotify "pre content" events.
