RDMA/rdmavt: Delete unnecessary NULL check
There is no need to check 'rdi->qp_dev' for NULL. The field 'qp_dev'
is created in rvt_register_device() which will fail if the 'qp_dev'
allocation fails in rvt_driver_qp_init(). Overwise this pointer
doesn't changed and passed to rvt_qp_exit() by the next step.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
