Ameer Hamza 5b93d1a218 L2ARC: Fix prev_hdr use-after-free in l2arc_write_sublist ...

prev_hdr is dereferenced after the sublist lock is dropped for write I/O
but nothing prevents it from being freed during that window. Eliminate
prev_hdr entirely and simplify persistent marker repositioning logic.
