[S390] xpram: remove __initdata attribute from module parameters

The module parameter 'devs' and 'sizes' are marked as __initdata. The
memory for the parameters are freed after module_init completed. This
can lead to kernel crashes in param_free_charp. Remove the __initdata
attribute to fix the problem.
