bnxt_en: Refactor logic to re-enable SRIOV after firmware reset detected.
Put the current logic in bnxt_open() to re-enable SRIOV after detecting firmware reset into a new function bnxt_reenable_sriov(). This call needs to be invoked in the firmware reset path also in the next patch. Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
