Alexey Khoroshilov 7777b1f795 mISDN: Fix memory leak in dsp_pipeline_build() ...

[ Upstream commit c6a502c229 ]

dsp_pipeline_build() allocates dup pointer by kstrdup(cfg),
but then it updates dup variable by strsep(&dup, "|").
As a result when it calls kfree(dup), the dup variable contains NULL.

Found by Linux Driver Verification project (linuxtesting.org) with SVACE.
