HID: prodikeys: Check presence of pm->input_ep82

Browse source

[ Upstream commit cee8337e1b ]

Fake USB devices can send their own report descriptors for which the
input_mapping() hook does not get called.  In this case, pm->input_ep82 stays
NULL, which leads to a crash later.

This does not happen with the real device, but can be provoked by imposing as
one.
