coredump: fix various invalid memory access

Previously, we did not check error from iovw_put(). If it fails, the
target iovw may have no iov or partial iovs from the journal importar.
So, the finalization may cause underflow and may access and free invalid
memory.

Follow-up for 946dc7c635f050129896d1515c08a81504af2421.
