Cristian Marussi c7f8852d42 firmware: arm_scmi: Fix late checks on pointer dereference
A few dereferences could happen before the iterator pointer argument was
checked for NULL, causing the following smatch warnings:

drivers/firmware/arm_scmi/driver.c:1214 scmi_iterator_run() warn: variable
dereferenced before check 'i' (see line 1210)

Fix by moving the checks early and dropping some unneeded local references.

No functional change.
