[PATCH] rawdev: fix device ID retrieval function prototype

[Nawal Kishor <nkishor@marvell.com>]

Fixed rte_rawdev_get_dev_id() function prototype and its usage.

Fixes: c88b3f2558ed ("rawdev: introduce raw device library")

Signed-off-by: Nawal Kishor <nkishor@marvell.com>

This patch fixes the return type of rte_rawdev_get_dev_id(). It would be good
to have it merged before the 25.11 release, as it corrects a user-visible API
bug and is a safe change.
