UBIFS: remount ro fixes
- preserve the idx_gc list - it will be needed in the same state, should UBIFS be remounted rw again - prevent remounting ro if we have switched to read only mode (due to a fatal error) Signed-off-by: Adrian Hunter <ext-adrian.hunter@nokia.com> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
