jffs2: Fix if/else empty body warnings

Browse Source 
When debug (print) macros are not enabled, change them to use the
no_printk() macro instead of <nothing>. This fixes gcc warnings when
-Wextra is used:

../fs/jffs2/nodelist.c:255:37: warning: suggest braces around empty body in an ‘else’ statement [-Wempty-body]
../fs/jffs2/nodelist.c:278:38: warning: suggest braces around empty body in an ‘else’ statement [-Wempty-body]
../fs/jffs2/nodelist.c:558:52: warning: suggest braces around empty body in an ‘else’ statement [-Wempty-body]
../fs/jffs2/xattr.c:1247:58: warning: suggest braces around empty body in an ‘if’ statement [-Wempty-body]
../fs/jffs2/xattr.c:1281:65: warning: suggest braces around empty body in an ‘if’ statement [-Wempty-body]

Builds without warnings on all 3 levels of CONFIG_JFFS2_FS_DEBUG.
