- Allow multiple functions with INTA.
- Removed the condition to allow only one vpath with INTA
- Ensure that the alarm bit in titan_mask_all_int register is cleared when
driver exits.

This patch fixes a case in the transmit completion code which was resulting
in pktgen hanging at the end of a run. The cause is due to the fact that
the ->cb[] area of an skb cannot be used in a network driver's transmit
path, as that area belongs to the network protocol. Pktgen hangs, as it
sends out the same packet multiple times, and vxge's use of this area of
the skb for a temporary list can only add the packet to the temporary list
once (while it may be on the queue many times). The fix is to remove this
abuse of skb->cb[]. Instead, skb pointers are placed into a temporary
stack array, and then free outside of the tx lock. This retains the smp
optimization of doing dev_kfree_skb() outside of the tx lock.

- Removed the code to bounds check the mss value. The hardware does bounds checking and
will not allow an oversized mss to lockup the transmit path.
