media: i2c: imx214: Rearrange control initialization

Smatch is confused by the control initialization logic. It assumes that
there can be a case where imx214->link_freq can be NULL and ctrls_init
returns 0.

Re-arrange the function to make smatch happy.

This patch fixes this smatch error:
drivers/media/i2c/imx214.c:1109 imx214_ctrls_init() error: we previously assumed 'imx214->link_freq' could be null (see line 1017)
