Toomas Soome f1624ed8c4 Bug 212114 - loader: zio_checksum_verify() must test spa for NULL pointer 
The issue was introduced with adding support for salted checksums, and
was revealed by bhyve userboot.so.

During pool discovery the loader is reading pool label from disks, and
at that time the spa structure is not yet set up, so the NULL pointer
is passed for spa. This condition must be checked to avoid the corruption
of the memory and NULL pointer dereference.

README 

$FreeBSD$

This directory contains various files derived from CDDL sources that
are used by the ZFS bootstrap:

    fletcher.c			checksum support
    sha256.c			checksum support
    lz4.c			compression support
    lzjb.c			compression support
    blkptr.c			ZFS embedded-data block pointers support
    zfssubr.c			checksum, compression and raidz support
    zfsimpl.h			mostly describing the physical layout

The files fletcher.c, lzjb.c, lz4.c, sha256.c and blkptr.c are largely identical
to the ZFS base code (with write support removed) and could be shared but that
might complicate future imports from Illumos.
