Fix the warning:
drivers/net/cxgb3/cxgb3_main.c: In function ‘offload_open’:
drivers/net/cxgb3/cxgb3_main.c:936: warning: ignoring return value of
 ‘sysfs_create_group’, declared with attribute warn_unused_result

Now the return value is checked; if sysfs_create_group() returns failure,
a warning is printed using dev_dbg, and the code continues as before.  Use
of dev_dbg ensures printk is not needlessly included unless desired for
debugging.
