ALSA: echoaudio - Eliminate use after free

Use the call to snd_card_free in the error handling code at the end of the
function, as in the other error cases.

A simplified version of the semantic patch that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@@
expression E,E2;
@@

snd_card_free(E)
...
(
  E = E2
|
* E
)
// </smpl>
