Subject: [PATCH 2/8] iwlwifi: mvm: global PM mode does not reset after FW crash

From: Ravi Darsi <[email protected]>

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.
