[Xen-devel] [PATCH] xen/unlzma: Fix build of stubdom unsafe decompressors

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

c/s b683d68c386 changed the packing attribute on struct lzma_header.  However,
this is 3rd library code used by stubdomains.

Revert the change to lzma_header alone to avoid needless divergence from its
source.
