[PATCH 4.4 133/268] bnxt_en: Check valid VNIC ID in bnxt_hwrm_vnic_set_tpa().

[Greg Kroah-Hartman]

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

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

From: Michael Chan <michael.chan@xxxxxxxxxxxx>

[ Upstream commit 3c4fe80b32c685bdc02b280814d0cfe80d441c72 ]

During initialization, if we encounter errors, there is a code path that
calls bnxt_hwrm_vnic_set_tpa() with invalid VNIC ID.  This may cause a
warning in firmware logs.

Fixes: c0c050c58d84 ("bnxt_en: New Broadcom ethernet driver.")
