The "test_gpio_process_events_multi_success" test currently hangs with
an update to a newer version of Rust. The code here tries to read the
value, locked, for each GPIO one by one. The values are updated in
another thread with the help of write lock.
More discussion around this issue can be found here.

Taking the lock only once fixes it for now.

The virtio-gpio driver at the guest performs virtio transaction right
from its probe() routine and without this patch, there is a chance that
the backend may miss the notification from the guest, as the
notification may be sent before the eventfd is set at the backend. This
flag makes the master side wait for reply from backend before proceeding
further for each operation.
