Subject: [PATCH] asan: abort in wasm_scan_name_function_section

Macros like READ_LEB128 in wasm-module.c that alter control flow are
evil.  Maintainers will break your code if you have hidden ways to
reach labels.

	* wasm-module.c (wasm_scan_name_function_section): Don't
	attempt to bfd_release NULL.
