[PATCH 4.4 022/149] nfc: s3fwrn5: add missing release on skb in s3fwrn5_recv_frame

[Greg Kroah-Hartman]

From: Navid Emamdoost <navid.emamdoost@xxxxxxxxx>

[ Upstream commit 1e8fd3a97f2d83a7197876ceb4f37b4c2b00a0f3 ]

The implementation of s3fwrn5_recv_frame() is supposed to consume skb on
all execution paths. Release skb before returning -ENODEV.
