[RFC PATCH 1/5] firmware_loader: Clear data and size in fw_free_paged_buf

[Russ Weight <russell.h.weight@intel.com>]

The fw_free_paged_buf() function resets the paged buffer information in
the fw_priv data structure. Additionally, clear the data and size members
of fw_priv in order to facilitate the reuse of fw_priv. This is being
done in preparation for enabling userspace to initiate multiple firmware
uploads using this sysfs interface.
