media: atomisp: gc0310: Use devm_kzalloc() for data struct
Use devm_kzalloc() to allocate the data struct. It is always free-ed as
the last step of probe-error-exit or remove, so it can be devm-managed.
This will make unwinding things easier when support is added to the gc0310
code to use standard GPIO APIs instead of the custom atomisp_gmin code.
This also allows dropping the out_free label and use direct return
on errors.
This may seem like a functional change since the out_free label also
did a v4l2_device_unregister_subdev() but at the 1 changed return
the device is not registered yet, so that always is a no-op and can
be dropped.
