Muhammad Husaini Zulkifli 06b412589e igc: Add lock to safeguard global Qbv variables ...

Access to shared variables through hrtimer requires locking in order
to protect the variables because actions to write into these variables
(oper_gate_closed, admin_gate_closed, and qbv_transition) might potentially
occur simultaneously. This patch provides a locking mechanisms to avoid
such scenarios.
