[Xen-devel] [PATCH] x86/psr: remove useless check in free_socket_resources

The check is useless because pointer arithmetic ensures "info" is
always non-zero.

Replace it with an ASSERT for socket_info. The only caller of
free_socket_resources already ensures socket_info is not NULL before
calling it.
