nl80211: Fix error path in if_indices_reason reallocation 

Commit 732b1d20ec ('nl80211: Clean up
ifidx properly if interface in a bridge is removed') added
drv->if_indices_reason array similarly to the previously used
drv->if_indices. However, it had a copy-paste error here on the error
path where a reallocation failure after at least one successful
reallocation would result in the drv->if_indices being overridden
instead of restoring drv->if_indices_reason to the old value. Fix this
by setting the correct variable on the error path. (CID 138514)
