[PATCH 7/9] ASoC: stm32: remove redundant pointers 'priv' and 'rtd'

[Colin King <colin.king@canonical.com>]

From: Colin Ian King <colin.king@canonical.com>

Pointer 'priv' is assigned and not used, removing this allows
the removal of pointer 'rtd'.

Cleans up clang warning:
warning: variable 'priv' set but not used [-Wunused-but-set-variable]
