octeon: use proper refs for roc item spec and mask

vnet flow enable is failing due to bogus bytes pointed by spec, mask
variables of roc_npc_flow_item structure. Using reference to local
variables defined in block scope is causing this. Moving the variable
declarations to function block scope fixes this issue.
