Subject: [PATCH 4.19 204/321] infiniband: bnxt_re: qplib: Check the return value of send_message

From: Aditya Pakki <pakki001@....edu>

[ Upstream commit 94edd87a1c59f3efa6fdf4e98d6d492e6cec6173 ]

In bnxt_qplib_map_tc2cos(), bnxt_qplib_rcfw_send_message() can return an
error value but it is lost. Propagate this error to the callers.
