Zheyu Ma 38bc2ebf34 atm: nicstar: register the interrupt handler in the right place 
[ Upstream commit 70b639dc41ad499384e41e106fce72e36805c9f2 ]

Because the error handling is sequential, the application of resources
should be carried out in the order of error handling, so the operation
of registering the interrupt handler should be put in front, so as not
to free the unregistered interrupt handler during error handling.

This log reveals it:
