As Sandeep shown [1], high priority RT per-cpu kthreads are

Switch EROFS_FS_PCPU_KTHREAD_HIPRI on by default if
EROFS_FS_PCPU_KTHREAD is on since it's the typical use cases for
EROFS_FS_PCPU_KTHREAD.
Also clean up unneeded sched_set_normal().

How about removing this config option?
I tend to leave it as is.
Thanks,
