[PATCH 4.4 078/342] iw_cxgb3: Fix incorrectly returning error on success

[Greg Kroah-Hartman]

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Hariprasad S <hariprasad@xxxxxxxxxxx>

commit 67f1aee6f45059fd6b0f5b0ecb2c97ad0451f6b3 upstream.

The cxgb3_*_send() functions return NET_XMIT_ values, which are
positive integers values. So don't treat positive return values
as an error.
