jffs2: mark __jffs2_dbg_superblock_counts() static

This function is only called locally and does not need to be global.
Since there is no external prototype, gcc warns about the non-static
definition:

fs/jffs2/debug.c:160:6: error: no previous prototype for '__jffs2_dbg_superblock_counts' [-Werror=missing-prototypes]
