sctp: Don't abort initialization when CONFIG_PROC_FS=n
This puts CONFIG_PROC_FS defines around the proc init/exit functions and also avoids compiling proc.c if procfs is not supported. Also make SCTP_DBG_OBJCNT depend on procfs.

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