qcacld-3.0: Return appropriate status code in sme_nan_request

After the NAN request message is posted to the SME queue in
sme_nan_request, the status of the scheduler API is ignored.
Success will be returned in the case of a failure during
posting the message. This may generate unexpected outcomes
during NAN testcases.

Return appropriate status code in sme_nan_request to the caller.
