crypto: hisilicon - Fix double free in sec_free_hw_sgl()
There are two problems in sec_free_hw_sgl():
First, when sgl_current->next is valid, @hw_sgl will be freed in the
first loop, but it free again after the loop.
Second, sgl_current and sgl_current->next_sgl is not match when
dma_pool_free() is invoked, the third parameter should be the dma
address of sgl_current, but sgl_current->next_sgl is the dma address
of next chain, so use sgl_current->next_sgl is wrong.
Fix this by deleting the last dma_pool_free() in sec_free_hw_sgl(),
modifying the condition for while loop, and matching the address for
dma_pool_free().
