Josh Triplett 82f050300b ext4: don't run ext4lazyinit for read-only filesystems ...

[ Upstream commit 426d15ad11 ]

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: 21175ca434 ("ext4: make prefetch_block_bitmaps default")
