[cacard 6/7] cac-aca: Favour g_return_val_if_fail over g_assert

[Christophe Fergeau <cfergeau@xxxxxxxxxx>]

Some g_assert are used to sanity-check input arguments of some methods.
g_return_val_if_fail() is more appropriate for that as it won't cause
the program using libcacard to terminate. The callers of these methods
are already checking the return value for NULL.
