[PATCH v3 03/18] cxl: Define process problem state area at attach time only

[Frederic Barrat]

Cxl kernel API was defining the process problem state area during
context initialization, making it possible to map the problem state
area before attaching the context. This won't work on a powerVM
guest. So do the logical thing, like in userspace: attach first, then
map the problem state area.
Remove calls to cxl_assign_psn_space during init. The function is
already called on the attach paths.
