scsi: aacraid: Drop redundant pci_enable_pcie_error_reporting() 

pci_enable_pcie_error_reporting() enables the device to send ERR_*
Messages.  Since commit f26e58bf6f ("PCI/AER: Enable error reporting when
AER is native"), the PCI core does this for all devices during enumeration,
so the driver doesn't need to do it itself.

Remove the redundant pci_enable_pcie_error_reporting() call from the
driver.

Note that this only controls ERR_* Messages from the device.  An ERR_*
Message may cause the Root Port to generate an interrupt, depending on the
AER Root Error Command register managed by the AER service driver.

Also remove pci_disable_pcie_error_reporting() from the .error_detected()
path, which was added by commit 5c63f7f710 ("aacraid: Added EEH support")
but looks unnecessary.  Error reporting will be disabled by the device
reset and will be re-enabled by the pci_restore_state() in
aac_pci_slot_reset().
