iwlwifi: pcie: set LTR to avoid completion timeout

Browse source

On some platforms, the preset values aren't correct and then we may
get a completion timeout in the firmware. Change the LTR configuration
to avoid that. The firmware will do some more complex reinit of this
later, but for the boot process we use ~250usec.
