cpukit/jffs2: Revert to non-granular locking
Revert JFFS2 to non-granular locking. This makes the superblock
available to the delayed work that it owns so that delayed work
processing can ensure that shared resources are being exclusively
accessed. This change only affects NAND systems. Moving forward with
granular locking will require a significant investment of time in
producing a test harness that doesn't require hardware such that this
can get a reasonable amount of test coverage.
