ice: re-order ice_mbx_reset_snapshot function

Browse source 
A future change is going to refactor the VF mailbox overflow detection
logic, including modifying ice_mbx_reset_snapshot and its callers. To make
this change easier to review, first move the ice_mbx_reset_snapshot
function higher in the ice_vf_mbx.c file.
