scsi: mpt3sas: Fix Sync cache command failure during driver unload

[ Upstream commit 9029a72500b95578a35877a43473b82cb0386c53 ]

This is to fix SYNC CACHE and START STOP command failures with
DID_NO_CONNECT during driver unload.

In driver's IO submission patch (i.e. in driver's .queuecommand()) driver
won't allow any SCSI commands to the IOC when ioc->remove_host flag is set
and hence SYNC CACHE commands which are issued to the target drives (where
write cache is enabled) during driver unload time is failed with
DID_NO_CONNECT status.

Now modified the driver to allow SYNC CACHE and START STOP commands to IOC,
even when remove_host flag is set.
