staging: gpib: tnt4882: remove unused variable

Browse Source 
Remove unused variable 'retval' in function 'tnt4882_update_status'.

A call to nec7210_update_status_nolock() is added as the status bits are written
to board->status in that function.

This change removes the following warning:

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