A caller may/may not pass the flags in qman enqueue multi API.
This patch adds a check on that flag and only accesses it if passed
by the caller.

From: Shreyansh Jain <shreyansh.jain@nxp.com>

While scanning for devices, the order in which devices appear is
different as compared to MAC sequence.
This can cause confusion for users and automated scripts.
This patch create a sorted list of devices.
