ALSA: echoaudio: Fix memory allocation

[ Upstream commit 9c6795a9b3cbb56a9fbfaf43909c5c22999ba317 ]

'commpage_bak' is allocated with 'sizeof(struct echoaudio)' bytes.
We then copy 'sizeof(struct comm_page)' bytes in it.
On my system, smatch complains because one is 2960 and the other is 3072.

This would result in memory corruption or a oops.
