HID: steam: Reject short reads
Steam Controller FEATURE reports encode the size of the message in the
message itself. Previously we were trusting that the size reported matched
the size we actually read, leading to a potential issue with short reads.
Instead, we should actually verify the length of the read.
Fixes: c164d6abf384 ("HID: add driver for Valve Steam Controller")
