nfp: correct cleanup related to DCB resources
This patch corrects two oversights relating to releasing resources
and DCB initialisation.
1. If mapping of the dcbcfg_tbl area fails: an error should be
propagated, allowing partial initialisation (probe) to be unwound.
2. Conversely, if where dcbcfg_tbl is successfully mapped: it should
be unmapped in nfp_nic_dcb_clean() which is called via various error
cleanup paths, and shutdown or removal of the PCIE device.
