tg3: Clarify semantics of TG3_IRQ_MAX_VECS

TG3_IRQ_MAX_VECS should be seen as the maximum number of vectors that
any device could be expected to use.  tp->irq_max represents the maximum
number of vectors the current device can use.  This patch clarifies the
semantics of the code to match the above description.
