RDMA/hfi1: Initialize debugfs after probe completes

Browse Source 
Commit ed6f653fe4 ("staging/rdma/hfi1: Fix debugfs access race") moved
debugfs creation after device initialization and IB registration so users
cannot access the files before the driver is ready. However, init_one()
still creates them before character device creation and SDMA startup
finish.

Move hfi1_dbg_ibdev_init() to the end of the successful probe path,
matching hfi1_dbg_ibdev_exit() as the first action in remove_one().
