RDMA/srp: Fix error handling in srp_add_port

Browse Source 
[ Upstream commit a3cbf68c69 ]

As comment of device_add() says, if device_add() succeeds, you should
call device_del() when you want to get rid of it. If device_add() has
not succeeded, use only put_device() to drop the reference count.

Add a put_device() call before returning from the function to decrement
reference count for cleanup.

Found by code review.
