staging: gpib: ni_usb: remove unused variable

Remove unused variable 'adr1_bits' in function 'parse_board_ibrd_readback'

Since the value of the variable 'i' is increased when 'adr1_bits' is set, the
'i++' post-increment was added in order to keep the value of 'i' right.

This change removes the following warning:

warning: variable ‘adr1_bits’ set but not used [-Wunused-but-set-variable]
