xen/x86: don't initialize cpu_data[]'s apicid field on generic code

Afaict, this is not only redundant with the intialization done in
drivers/xen/core/smpboot.c, but actually results - at least for
secondary CPUs - in the Xen-specific value written to be later
overwritten with whatever the generic code determines (with no
guarantee that the two values are identical).

16 Stream Control Transmission Protocol
18 From RFC 2960 <http://www.ietf.org/rfc/rfc2960.txt>.
20 "SCTP is a reliable transport protocol operating on top of a
21 connectionless packet network such as IP. It offers the following
22 services to its users:
24 -- acknowledged error-free non-duplicated transfer of user data,
25 -- data fragmentation to conform to discovered path MTU size,
26 -- sequenced delivery of user messages within multiple streams,
27 with an option for order-of-arrival delivery of individual user
28 messages,
29 -- optional bundling of multiple user messages into a single SCTP
30 packet, and
31 -- network-level fault tolerance through supporting of multi-
32 homing at either or both ends of an association."
34 To compile this protocol support as a module, choose M here: the
35 module will be called sctp.
37 If in doubt, say N.

52 If you say Y, this will enable debugging support for counting the
53 type of objects that are currently allocated. This is useful for
54 identifying memory leaks. If the /proc filesystem is enabled this
55 debug information can be viewed by
56 'cat /proc/net/sctp/sctp_dbg_objcnt'

65 HMAC algorithm to be used during association initialization. It
66 is strongly recommended to use HMAC-SHA1 or HMAC-MD5. See
67 configuration for Cryptographic API and enable those algorithms
68 to make usable by SCTP.
