ASoC: topology: fix soc_tplg_fe_link_create() - link->dobj initialization
order
The code which checks the return value for snd_soc_add_dai_link() call
in soc_tplg_fe_link_create() moved the snd_soc_add_dai_link() call before
link->dobj members initialization.
While it does not affect the latest kernels, the old soc-core.c code
in the stable kernels is affected. The snd_soc_add_dai_link() function uses
the link->dobj.type member to check, if the link structure is valid.
Reorder the link->dobj initialization to make things work again.
It's harmless for the recent code (and the structure should be properly
initialized before other calls anyway).
The problem is in stable linux-5.4.y since version 5.4.11 when the
upstream commit 76d270364932 was applied.

snd_soc_add_dai_link()")
