From: Ravi Darsi <ravi.darsi@intel.com>

When The driver in D3 and FW crash happens, trans->system_pm_mode
is  not reset to IWL_PLAT_PM_MODE_DISABLED which causes the driver
not to send INIT conmmands and D3 resume fails.

This patch contains the fix for resetting trans->system_pm_mode to
IWL_PLAT_PM_MODE_DISABLED and D3 resume is successful.
