Subject: [RFC PATCH][RESEND] Fusion MPT: disable pci device when mpt map 
resoures failed


when probe a pci device, first we enable it, and disable it when
some error happened in the following process, because the power
state of the device is set to D0, and if MSI is disabled,
we will allocate irq and register gsi for this device in the enable process.

In function mpt_mapresources(MPT_ADAPTER *ioc), it forgot disable the
pci device when error happened, the irq and gsi will never be released.
this patch will fix it.
