ALSA: echoaudio: remove redundant initialization of pointer 'pipe'

Browse Source 
The pointer 'pipe' is being initialized with a value that is never
read and it is re-assigned later, hence the initialization is redundant
and can be removed. Also remove pointer 'runtime' as it is no longer
required.

Cleans up clang warning:
sound/pci/echoaudio/echoaudio.c:740:20: warning: Value stored to 'pipe'
during its initialization is never read
