mmc: core: Prevent accessing user space buffer directly
In mmc_wr_pack_stats_read(), userspace buffer is directly accessed
which is violating PAN (Privilege Access Never).
So to prevent this, data which needs to be copied to user buffer is
gathered into a local buffer and at the end, this local buffer
contents are copied back to buffer supplied from user space using
copy_to_user().
