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.
