[PATCH v2] scsi: hpsa: Fix memory leak in hpsa_undo_allocations_after_kdump_soft_reset()

[Zilin Guan]

The h->reply_map is allocated in hpda_alloc_ctlr_info() via kcalloc().
If the controller reset fails during initialization in hpsa_init_one(),
hpsa_undo_allocations_after_kdump_soft_reset() is called to clean up
resources. However, this function frees the controller structure h but
fails to free h->reply_map, leading to a memory leak.

Fix this by freeing h->reply_map before freeing h in the cleanup function.
