Subject: [PATCH 5.0 24/32] bnxt_en: Fix statistics context reservation logic.

From: Michael Chan <michael.chan@...adcom.com>

[ Upstream commit 3f93cd3f098e284c851acb89265ebe35b994a5c8 ]

In an earlier commit that fixes the number of stats contexts to
reserve for the RDMA driver, we added a function parameter to pass in
the number of stats contexts to all the relevant functions.  The passed
in parameter should have been used to set the enables field of the
firmware message.

Fixes: 780baad44f0f ("bnxt_en: Reserve 1 stat_ctx for RDMA driver.")
