Kees Cook be64d4b114 crypto: hisilicon: Wipe entire pool on error 
[ Upstream commit aa85923a95 ]

To work around a Clang __builtin_object_size bug that shows up under
CONFIG_FORTIFY_SOURCE and UBSAN_BOUNDS, move the per-loop-iteration
mem_block wipe into a single wipe of the entire pool structure after
the loop.
