atm: nicstar: fix if-statement empty body warning
When debugging via PRINTK() is not enabled, make the PRINTK()
macro be an empty do-while block.
Thix fixes a gcc warning when -Wextra is set:
../drivers/atm/nicstar.c:1819:23: warning: suggest braces around empty body in an ‘else’ statement [-Wempty-body]
I have verified that there is no object code change (with gcc 7.5.0).
