hpsa: call pci_release_regions after pci_disable_device

hpsa: call pci_release_regions after pci_disable_device

Despite the fact that PCI devices are enabled in this order:
    1. pci_enable_device
    2. pci_request_regions

    Documentation/PCI/pci.txt specifies that they be undone
    in this order
    1. pci_disable_device
    2. pci_release_regions

    Tested by injecting error in the call to pci_enable_device
    in hpsa_init_one -> hpsa_pci_init:
    [    9.095001] hpsa 0000:04:00.0: failed to enable PCI device
    [    9.095005] hpsa: probe of 0000:04:00.0 failed with error -22
    (-22 is -EINVAL)
    and then in the call pci_request_regions:
    [    9.178623] hpsa 0000:04:00.0: failed to obtain PCI resources
    [    9.178671] hpsa: probe of 0000:04:00.0 failed with error -16
    (-16 is -EBUSY)

    and then by adding
        reset_devices
    to the kernel command line and inject errors into the two
    calls to pci_enable_device and the call to pci_request_regions
    in hpsa_init_one -> hpsa_init_reset_devices.

    (inject on 6th call, 1st to hpsa2)
    [   62.413750] hpsa 0000:04:00.0: Failed to enable PCI device

    (inject on 7th call, 2nd to hpsa2)
    [   62.807571] hpsa 0000:04:00.0: failed to enable device.

    (inject on 8th call, 3rd to hpsa2)
    [   62.697198] hpsa 0000:04:00.0: failed to obtain PCI resources
    [   62.697234] hpsa: probe of 0000:04:00.0 failed with error -16

    The reset_devices path calls return -ENODEV on failure
    rather than passing the result, which apparently doesn't
    cause the pci driver to print anything.
