qseecom: change compat_qseecom_wipe_key_req for compat_qseecom operation 



wipe_key_flag was missing in the definition of compat_qseecom_wipe_key_req,
then wipe key operation failed due to compat ioctl operation mismatch on
32bit userspace and 64 bit kernel system. We then make a change to add the
field of wipe_key_flag for compat_qseecom operation.
