[PATCH] boot: don't use the nfs:// mount path after freeing it

[Ahmad Fatoum]

We free nfspath, while there is still a dangling reference to it in
the `name' variable:

	nfspath = parse_nfs_url(name);
	if (nfspath)
		name = nfspath;
	...
	free(nfspath);

	if (IS_ENABLED(CONFIG_COMMAND_SUPPORT) && !found) {
		const char *path;

		if (*name != '/')

Fix this by freeing it at the end of function.
