hv:Replace dynamic memory with static for sbuf

Browse Source 
--Config LOG_BUF_SIZE 256KB for per cpu
--Replace 'calloc' with static array for sbuf
--Rename 'alloc_earlylog_sbuf' to 'init_earlylog_sbuf'
--Remove deadcode sbuf_free

v2-->v3:
 -- put the buffer into per_cpu data structure
v1-->v2:
 -- add 'is_early_logbuf' in percpu data structure used for
    check if need to do 'do_copy_earlylog'
