[TG3]: Fix tg3_restart_ints()
tg3_restart_ints() is called to re-enable interrupts after tg3_poll() has finished all the work. It calls tg3_cond_int() to force an interrupt if the status block updated bit is set. The updated bit will be set if there is a new status block update sometime during tg3_poll() and it can be very often. The worst part is that even if all the work has been processed, the updated bit remains set and an interrupt will be forced unnecessarily. The fix is to call tg3_has_work() instead to determine if new work is posted before forcing an interrupt. The way to force an interrupt is also changed to use "coalesce_now" instead of "SETINT". The former is generally a safer way to force the interrupt. Also deleted the first parameter to tg3_has_work() which is unused.
