With EC overwrites maturing, the kernel client will be getting exposed
to potentially very wide EC pools. While "min(pi->size, X)" works fine
when the cluster is stable and happy, truncating OSD sets interferes
with resend logic (ceph_is_new_interval(), etc). Abort the mapping if
the pool is too wide, assigning the request to the homeless session.
