ASoC: SOF: icp3-dtrace: Fix wrong kfree() usage

trace_filter_parse() allocs memory for *out and when
-ENOMEM is returned, caller function, dfsentry_trace_filter_write()
trying to freed this memory.

After this patch, the memory is freed in trace_filter_parse()
before -EINVAL returned. In caller function removed kfree(elms)
from error label
