Wang Hai 3d5831a40d media: msi001: fix possible null-ptr-deref in msi001_probe()

I got a null-ptr-deref report:

BUG: kernel NULL pointer dereference, address: 0000000000000060
...
RIP: 0010:v4l2_ctrl_auto_cluster+0x57/0x270
...
Call Trace:
 msi001_probe+0x13b/0x24b [msi001]
 spi_probe+0xeb/0x130
...
 do_syscall_64+0x35/0xb0

In msi001_probe(), if the creation of control for bandwidth_auto
fails, there will be a null-ptr-deref issue when it is used in
v4l2_ctrl_auto_cluster().

Check dev->hdl.error before v4l2_ctrl_auto_cluster() to fix this bug.
