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.

I find this reset statement redundant here.

Hi Markus,

Thanks for the review.

I originally added the NULL assignment to maintain consistency with the 
existing code style in this function, but I agree it is redundant here.

I will remove it in v2.
