mISDN: Fix memory leak in dsp_hwec_enable()
dsp_hwec_enable() allocates dup pointer by kstrdup(arg),
but then it updates dup variable by strsep(&dup, ",").
As a result when it calls kfree(dup), the dup variable may be
a modified pointer that no longer points to the original allocated
memory, causing a memory leak.
The issue is the same pattern as fixed in commit c6a502c22999
("mISDN: Fix memory leak in dsp_pipeline_build()").
Fixes: 9a4381618262 ("mISDN: Remove VLAs")
