ixgbe: increase VF reset timeout

DPDK commit meesage

When VF issues a reset to PF there is a 50 msec wait plus an additional
max of 1 msec (200 * 5us) for the PF to indicate the reset is complete
before timeout.

In some cases, it is seen that the reset is timing out, in which case
the reset does not complete and an error is returned.

In order to account for this, continue to wait an initial 50 msecs, but
then allow a max of an additional 50 msecs (10,000 * 5us) for the
command to complete.
