[PATCH] media: pxa_camera: remove an impossible condition

[Dan Carpenter <dan.carpenter@oracle.com>]

It's not possible for "pcdev->mclk" to be zero because we check for
that earlier and set it to 20000000 in that situation.  If it were
possible, that would be a problem because it could have lead to an Oops
in the error handling when we call v4l2_clk_unregister(pcdev->mclk_clk);
