eth: bnxt: request unconditional ops lock

netdev_lock_ops conditionally grabs instance lock when queue_mgmt_ops
is defined. However queue_mgmt_ops support is signaled via FW
so we can sometimes boot without queue_mgmt_ops being set.
This will result in bnxt running without instance lock which
the driver now heavily depends on. Set request_ops_lock to true
unconditionally to always request netdev instance lock.
