ALSA: echoaudio: Avoid non-standard macro usage

Browse source 
Pass the device pointer from the PCI pointer directly, instead of a
non-standard macro.  The macro didn't give any better readability.

Also slightly refactor the code (drop the return value check from the
preallocation) as it never returns an error.
