pci_enable_pcie_error_reporting() enables the device to send ERR_*
Messages. Since commit f26e58bf6f54 ("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. Also remove the corresponding pci_disable_pcie_error_reporting()
from the driver .remove() path.
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.

[ commit c5c440bbff86 upstream ]
Backport the change from a previous commit to kernel versions prior to
v6.0, where commit f26e58bf6f54 ("PCI/AER: Enable error reporting when
AER is native") hasn't been introduced.
When target mode is enabled, the pci_irq_get_affinity() function may return
a NULL value in qla_mapq_init_qp_cpu_map() due to the qla24xx_enable_msix()
code that handles IRQ settings for target mode. This leads to a crash due
to a NULL pointer dereference.
This patch fixes the issue by adding a check for the NULL value returned by
pci_irq_get_affinity() and introducing a 'cpu_mapped' boolean flag to the
qla_qpair structure, ensuring that the qpair's CPU affinity is updated when
it has not been mapped to a CPU.
Fixes: 1d201c81d4cc ("scsi: qla2xxx: Select qpair depending on which CPU post_cmd() gets called")
