[PATCH] 9pfs: fix inode sequencing in 'synth' driver

The 'synth' driver's root node and the 'synth' driver's first subdirectory node falsely share the same inode number (zero), which makes it impossible for 9p clients (i.e. 9p test cases) to distinguish root node and first subdirectory from each other by comparing their QIDs (which are derived by 9p
