Subject: [PATCH] Input: zforce - remove unnecessary payload data checks

The function zforce_read_packet() reads 2 values (bytes) of payload
header, validates them and then proceeds to read the payload body.
The function stores all these in a u8 buffer.

The PAYLOAD_LENGTH check seems to be trying to detect an overflow error.
However, since we are just reading a u8 value from the buffer, these
checks are unnecessary and we should simply compare against zero.
