scsi: mpi3mr: Fix hibernation issue

BugLink: https://bugs.launchpad.net/bugs/1967116
Hibernation operation fails when it is issued for second time. This is
because the driver is trying to release the IOC's PCI resources after
setting power state to D3.

Set the IOC's power state to D3 only after releasing the IOC's PCI
resources.
