zfs_vnops_os.c: Move a vput() to after zfs_setattr_dir()
Without this patch, the following crash can occur when
a file system is configured with "xattr=dir".

VNASSERT failed: locked not true at
 /posix-acl/freebsd-rdma/sys/kern/vfs_subr.c:5786 (assert_vop_locked)

This patch fixes the problem by moving the vput() call for
attrzp to after the zfs_setattr_dir() call that takes it as
an argument.
