rGe59d4ec66fca: ufshci: handle a recovery reset before the SIM attach

Summary

When the first start attempt fails early, the recovery reset
runs the start sequence again without a SIM. That pass still
looked up the WLUN, so it dereferenced a NULL SIM and panicked.

Attach the SIM whenever it does not exist yet. Also make the
WLUN lookup return NULL when there is no SIM.
