Add missing skb->dev assignment in Frame Relay RX code.

Hi Jeff,

How about the Frame-Relay fix, would you like me to repost it?

Alternatively you can get it from (based on 2.6.25):
git://git.kernel.org/pub/scm/linux/kernel/git/chris/linux-2.6.git hdlc-fixes

aka (on *.kernel.org):
/pub/scm/linux/kernel/git/chris/linux-2.6.git	hdlc-fixes

It contains:
$ git-diff --stat v2.6.25
 drivers/net/wan/hdlc_fr.c |    1 +
 1 files changed, 1 insertions(+), 0 deletions(-)

I'd be glad if it makes it to 2.6.26, it's a) obvious,
b) security-related, c) extra short, d) nobody objected

Thanks in advance.
