display EFGH sends in proc file for audigy

Currently we only display the first four sends even on the Audigy which has 8 sends. This obscures the fact that we set sends EFGH all to zero by default which is technically illegal. (Though it seems to work, the kX Windows driver sets these last 4 sends to high channels (62-24) and never sets two sends to the same address as the header file instructs).

This patch adds display of sends EFGH in the /proc file.

Disregard this patch. It has a stupid typo, and besides it turns out the display of EFX send routing in the /proc file was bogus to begin with. This is a per channel register, but it is only ever displayed for channel 0. Not very useful.

I will incorporate a fix for this into the per channel register dump patch.
