media: stm32-csi: Fix dereference before NULL check
commit 80eaf32672871bd2623ce6ba13ffc1f018756580 upstream.
In 'stm32_csi_start', 'csidev->s_subdev' is dereferenced directly while
assigning a value to the 'src_pad'. However the same value is being
checked against NULL at a later point of time indicating that there
are chances that the value can be NULL.
Move the dereference after the NULL check.
Fixes: e7bad98c205d1 ("media: v4l: Convert the users of v4l2_get_link_freq to call it on a pad")
