nvme/rdma: retrieve CAP during ctrlr_construct

Browse Source 
Fill in the cached copy of CAP in the generic NVMe controller to match
the PCIe transport.

This is not really early enough, since CAP is used during the reset
process to determine the reset timeout, but that will have to be fixed
separately by rearranging some of the transport callbacks.
