This patch fixes this issue by retrying a smaller MTU
when MAX_MTU is too large.
Oh yes, I missed that when I tried to make code look compact.
Thanks for pointing it out.

Hi Ben,
Yes, this is GRE-specific, somehow gre_sys doesn't support current MTU which
is 65000.
`make check-kmod` no. 11 and 21 fail due to this issue.
On the kernel side, the error shows up as:
[ 6135.11] gre_sys: Invalid MTU 65000 requested, hw max 1500
It reflects to userspace as error be

When MAX_MTU is larger than hw supported max MTU,
dpif_netlink_rtnl_create will fail. This leads to
testing failure '11: datapath - ping over gre tunnel'
in 'make check-kmod'.
This patch fixes this issue by retrying a smaller MTU
when MAX_MTU is too large.
