Linux: Initialize zp in zfs_setattr_dir

Browse Source 
The value of zp is used without having been initialized under some
conditions.  Initialize the pointer to NULL.

Add a regression test case using chown in acl/posix.  However, this is
not enough because the setup sets xattr=sa, which means zfs_setattr_dir
will not be called.  Create a second group of acl tests in acl/posix-sa
duplicating the acl/posix tests with symlinks, and remove xattr=sa from
the original acl/posix tests.  This provides more coverage for the
default xattr=on code.

The use of system attribute based xattrs is strongly encouraged for users of
SELinux or POSIX ACLs. Both of these features heavily rely of extended
SELinux or POSIX ACLs. Both of these features heavily rely on extended
attributes and benefit significantly from the reduced access time.
