[PATCH v6 5/5] brcmfmac: don't warn user if requested nvram fails

["Luis R. Rodriguez" <mcgrof@kernel.org>]

The requested nvram is optional, don't nag users about this.
Additionally, the new driver data API enables us to let the API
deal with the freeing of the nvram for us if we happen to free
it immediately on the consumer callback, this driver does that
so take advantage of this feature.

Originally based on patches by Rafał Miłecki.
