Fix a critical regression in 71be6bb5 causing multiple API failuresjbakita-wip
Instead of printing the read in `nvdebug_reg32_read()`, another read was being performed, using the first read value as the register offset! This is a mistaken incomplete removal of the old pre-error- -handling logic in 71be6bb5. This caused any APIs using this function to not work by returning bizzare or incorrect values, or crashing the system on Jetson boards.
