md/md-llbitmap: clamp state-machine walks to tracked bits
llbitmap_state_machine() can be called with an end bit beyond
llbitmap->chunks. In particular, llbitmap_cond_end_sync() passes
sector >> chunkshift, and sector can reach the tracked boundary
exactly.
Clamp the state-machine range to llbitmap->chunks so it cannot walk
past the tracked bitmap.
