Eric Biggers a0f044f025 crypto: user - fix leaking uninitialized memory to userspace ...

commit f43f39958b upstream.

All bytes of the NETLINK_CRYPTO report structures must be initialized,
since they are copied to userspace.  The change from strncpy() to
strlcpy() broke this.  As a minimal fix, change it back.
