bus: mhi: host: pci_generic: Drop redundant pci_enable_pcie_error_reporting()
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.
