Subject: bnxt_en: Fix the 'Invalid VF' id check in bnxt_vf_ndo_prep routine.

From: Venkat Duvvuru <[email protected]>

[ Upstream commit 78f300049335ae81a5cc6b4b232481dc5e1f9d41 ]

In bnxt_vf_ndo_prep (which is called by bnxt_get_vf_config ndo), there is a check for "Invalid VF id". Currently, the check is done against max_vfs. However, the user doesn't always create max_vfs. So, the check should be against the created number of VFs. The number of bnxt_vf_info structures that are allocated in bnxt_alloc_vf_resources routine is the "number of requested VFs". So, if an "invalid VF id" falls between the requested number of VFs and the max_vfs, the driver will be dereferencing an invalid pointer.
