Vaibhav Jain c335b49379 cxl: Wrap iterations over afu slices inside 'afu_list_lock' 
commit edeb304f659792fb5bab90d7d6f3408b4c7301fb upstream.

Within cxl module, iteration over array 'adapter->afu' may be racy
at few points as it might be simultaneously read during an EEH and its
contents being set to NULL while driver is being unloaded or unbound
from the adapter. This might result in a NULL pointer to 'struct afu'
being de-referenced during an EEH thereby causing a kernel oops.

This patch fixes this by making sure that all access to the array
'adapter->afu' is wrapped within the context of spin-lock
'adapter->afu_list_lock'.

Fixes: 9e8df8a219 ("cxl: EEH support")
