[PATCH] ALSA: echoaudio: remove unused variable

[Andres Urian Florez <andres.emb.sys@xxxxxxxxx>]

This patch cleans up the code in the __snd_echo_probe function of the
echoaudio.c driver by removing the unused variable i and moving the
declaration of the loop variable i inside the foor loops where it is
used
