Shida Zhang 3ef825dfd4 bcache: use bio cloning for detached device requests ...

Previously, bcache hijacked the bi_end_io and bi_private fields of
the incoming bio when the backing device was in a detached state.
This is fragile and breaks if the bio is needed to be processed by
other layers.

This patch transitions to using a cloned bio embedded within a private
structure. This ensures the original bio's metadata remains untouched.
