brcmfmac: add possibility to obtain firmware error

The feature module needs to evaluate the actual firmware error return
upon a control command. This adds a flag to struct brcmf_if that the
caller can set. This flag is checked to determine the error code that
needs to be returned.

Fixes: b69c1df472 ("brcmfmac: separate firmware errors from i/o errors")
