[JFFS2] Fix cross-endian build.
When compiling a LE-capable JFFS2 on PowerPC, wbuf.c fails to compile: fs/jffs2/wbuf.c:973: error: braced-group within expression allowed only inside a function fs/jffs2/wbuf.c:973: error: initializer element is not constant fs/jffs2/wbuf.c:973: error: (near initialization for ‘oob_cleanmarker.magic’) fs/jffs2/wbuf.c:974: error: braced-group within expression allowed only inside a function fs/jffs2/wbuf.c:974: error: initializer element is not constant fs/jffs2/wbuf.c:974: error: (near initialization for ‘oob_cleanmarker.nodetype’) fs/jffs2/wbuf.c:975: error: braced-group within expression allowed only inside a function fs/jffs2/wbuf.c:976: error: initializer element is not constant fs/jffs2/wbuf.c:976: error: (near initialization for ‘oob_cleanmarker.totlen’) Provide constant_cpu_to_je{16,32} functions, and use them for initialising the offending structure.
