Tools: Testbench: Fix ASRC component load

Before the fix the comp->core in ipc_comp_new() is garbage
and the check for maximum core count fails. The pointer to
struct asrc should be passed instead of address of pointer.

Fixes:	d9f9340
	("tplg_parser: split out testbench logic and partition
	features per file.")
