If the firmware is incommunicado for whatever reason the driver
will wait forever during initialisation, causing all sorts
of hangcheck timers to trigger.
We should rather wait for a defined time, and give up on the
command if no response was received.

megasas_get_map_info() might fail, after which it'll be
pointless to call megasas_sync_map_info().
So update megasas_get_map_info() to correctly handle errors
and call megasas_sync_map_info() only if no error occurred.

Hi all,
recently I've enabled VT-d on one of my systems, which happened to have
one of the latest Megaraid SAS cards (Fury) installed.
And it failed miserably due to invalid DMAR tables.
Which would be okay, if just the HBA failed to initialize.
But the entire system stalled as the megaraid_sas

Hi Hannes,
Just want to chime in to clarify that in the case of a 'device reset', I think
the driver's use of LUN Reset to the Smart Array controller is the correct
choice here. This is because the 'device' is actually a single logical unit on
