nic_uio: fix thread structure compatibility for future FreeBSD

Replace d_thread_t with struct thread in nic_uio.

Ref: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=196691
Quote:
"The d_thread_t typedef is a compat shim to support FreeBSD 4.x.
I'm planning to remove this shim from 11 and dpdk is very unlikely

ixgbevf: fix link state

This patch fixes checking the link state of a virtual function. If the
state has already been checked, it does not need to be checked
again. Previously, get_link_status in the ixgbe_hw struct was used to
track if the information had already been retrieved, but this field
was always set to false (signifying that the information was
up-to-date). The problem was introduced by commit 8ef32003 which was
part of a patch set to update the ixgbe portion of the PMD. This patch
does not break consistency with the ixgbevf driver. Instead, it fixes
the problem at the level of DPDK.

Applications that rely on the reported link speed could fail without
this patch. The qos_sched example application provided with DPDK did
not run when virtual functions were used. The output for this example
application is shown below:

EAL: Error - exiting with code: 1
  Cause: Unable to config sched subport 0, err=-2

The problem and the effect of the patch can been seen by running the
l2fwd example application using the following command:

sudo ./build/l2fwd -c 0x3 -n 4 -- -p 0x3 -T 0
