net/i40e: fix logging on VF close

When launch testpmd with VF and quit testpmd, there'll
be lots of messages "i40evf_handle_aq_msg(): Request 0
is not supported yet", which are triggered during VF
reset and VF needn't do anything. So cancel alarm handler
before VF reset to ignore the admin queue messages.

Fixes: e0e6a7f2154e ("net/i40e: cancel alarm handler at the end of closure")
