soc: qcom: pdr: Avoid uninitialized use of found in pdr_indication_cb
Clang warns:
../drivers/soc/qcom/pdr_interface.c:316:2: warning: variable 'found' is
used uninitialized whenever 'for' loop exits because its condition is
false [-Wsometimes-uninitialized]
list_for_each_entry(pds, &pdr->lookups, node) {

../include/linux/list.h:624:7: note: expanded from macro
'list_for_each_entry'
&pos->member != (head);
^~~~~~~~~~~~~~~~~~~~~~

occurs here
if (!found)

../drivers/soc/qcom/pdr_interface.c:316:2: note: remove the condition if
it is always true
