IB/core: Fix possible memory leak in cma_resolve_iboe_route() 

'work' and 'route->path_rec' are malloced in cma_resolve_iboe_route()
and should be freed before leaving from the error handling cases,
otherwise it will cause memory leak.

Fixes: 200298326b ('IB/core: Validate route when we init ah')
