In GH issue #1940 cppcheck warns about a possible null-dereference in check_user() when DEBUG_AUTH is enabled. Indeed, <ep> may potentially be NULL because upon error crypt_r() and crypt() may return a null pointer. However it's not directly derefenced, it is only passed to printf() with '%s' fmt. While it is in practice fine with the printf implementations we care about (that check strings against null before printing them), it is undefined behavior according to the spec, hence the warning. Let's check <ep> before passing it to printf. This should partly solve GH #1940.
