ext4: don't run ext4lazyinit for read-only filesystems
On a read-only filesystem, we won't invoke the block allocator, so we
don't need to prefetch the block bitmaps.
This avoids starting and running the ext4lazyinit thread at all on a
system with no read-write ext4 filesystems (for instance, a container VM
with read-only filesystems underneath an overlayfs).
Fixes: 21175ca434c5 ("ext4: make prefetch_block_bitmaps default")
