jffs2: avoid Wempty-body warnings
Building with W=1 shows a few warnings for empty macros: fs/jffs2/scan.c: In function 'jffs2_scan_xattr_node': fs/jffs2/scan.c:378:66: error: suggest braces around empty body in an 'if' statement [-Werror=empty-body] 378 | jffs2_sum_add_xattr_mem(s, rx, ofs - jeb->offset); | ^ fs/jffs2/scan.c: In function 'jffs2_scan_xref_node': fs/jffs2/scan.c:434:65: error: suggest braces around empty body in an 'if' statement [-Werror=empty-body] 434 | jffs2_sum_add_xref_mem(s, rr, ofs - jeb->offset); | ^ fs/jffs2/scan.c: In function 'jffs2_scan_eraseblock': fs/jffs2/scan.c:893:88: error: suggest braces around empty body in an 'if' statement [-Werror=empty-body] 893 | jffs2_sum_add_padding_mem(s, je32_to_cpu(node->totlen)); | ^ Change all these macros to 'do { } while (0)' statements to avoid the warnings and make the code a little more robust.
