HID: steam: Prevent NULL pointer dereference in steam_{recv,send}_report
commit cd11d1a6114bd4bc6450ae59f6e110ec47362126 upstream.
It is possible for a malicious device to forgo submitting a Feature
Report. The HID Steam driver presently makes no prevision for this
and de-references the 'struct hid_report' pointer obtained from the
HID devices without first checking its validity. Let's change that.
