[PATCH v2] net/idpf: fix compiling error in CentOS 7

[beilei.xing at intel.com]

From: Beilei Xing <beilei.xing at intel.com>

There's build error with clang 3.4.2 in CentOS 7:

drivers/net/idpf/idpf_vchnl.c:141:13: error: comparison of constant
522 with expression of type 'enum virtchnl_ops' is always false
[-Werror,-Wtautological-constant-out-of-range-compare]

Fixed the compiling error in the patch.

Fixes: 549343c25db8 ("net/idpf: support device initialization")

Signed-off-by: Beilei Xing <beilei.xing at intel.com>

v2 change: modify enum virtchnl_ops with uint32_t in header file.
