[Intel-wired-lan] [STABLE 4/4] ice: Set timeout when disabling queues

This patch is a backport of a single line of code from mainline
commit ddf30f7ff840 ("ice: Add handler to configure SR-IOV")

Queues are disabled during module unload using the ice_aqc_opc_dis_txqs
admin queue command. On the latest firmware, this command fails with
the following message: "Failed to disable LAN Tx queues, error: -100"

This patch fixes this issue by setting the timeout field in the command
descriptor.
