net/fm10k: fix logical port delete

When closing port, we need to send mailbox messages to switch manager
to reset multicast mode and delete logical port. In the latest IES_SDK,
e.g. v4.3.3, switch takes longer time to handle these mailbox messages.

So this patch adds longer delay to accommodate this change. Otherwise,
the mailbox will be closed before all the messages are handled, as a
result, the logical port remains in switch manager after port is closed.
