nfs: fix null checking in nfs_get_option_str()
The following null pointer check is broken.
*option = match_strdup(args);
return !option;
The pointer `option' must be non-null, and thus `!option' is always false.
Use `!*option' instead.
The bug was introduced in commit c5cb09b6f8
("Cleanup: Factor out some
cut-and-paste code.").
