4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Vikas Gupta <vikas.gupta@xxxxxxxxxxxx>
[ Upstream commit c58387ab1614f6d7fb9e244f214b61e7631421fc ]
Fix bug in the error code path when bnxt_request_irq() returns failure.
bnxt_disable_napi() should not be called in this error path because
NAPI has not been enabled yet.
Fixes: c0c050c58d84 ("bnxt_en: New Broadcom ethernet driver.")
