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.
