wifi: iwlwifi: mvm: trigger PCI re-enumeration in case of PLDR sync
When doing the PLDR flow, the fw goes through a re-read and needs
PCI re-enumeration in order to recover. In this case, skip the mac
start retry and fw dumps as all the fw and registers are invalid
until the PCI re-enumeration.
In addition, print the register that shows the re-read counter
when loading the fw.
