erofs: use HIPRI by default if per-cpu kthreads are enabled
As Sandeep shown [1], high priority RT per-cpu kthreads are typically helpful for Android scenarios to minimize the scheduling latencies. 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().
