[PATCH v1] erofs: use raw_smp_processor_id() to get buffer from global buffer pool

erofs will decompress in the preemptible context (kworker or per cpu thread). As smp_processor_id() cannot be used in preemptible contexts, use raw_smp_processor_id() instead to index into global buffer pool. Reported-by: syzbot+27cc650ef45b379df...@syzkaller.appspotmail.com Fixes: 7a7513292cc6
