ALSA: echoaudio: Fix improper return value in function load_asic

When the second call to load_asic_generic() fails in function
load_asic(), "false" is returned. The real value of "false" is 0, which
indicates success in the context. As a result, the execution status and
the return value may be inconsistent. This patch fixes the bug.
