Pull erofs fixes from Gao Xiang:
 "One patch addresses a null-ptr-deref issue reported by syzbot weeks
  ago, which is caused by the new long xattr name prefix feature and
  needs to be fixed.

  The remaining two patches are minor cleanups to avoid unnecessary
  compilation and adjust per-cpu kworker configuration.

  Summary:

   - Fix null-ptr-deref related to long xattr name prefixes

   - Avoid pcpubuf compilation if CONFIG_EROFS_FS_ZIP is off

   - Use high priority kthreads by default if per-cpu kthread workers
     are enabled"
