If an error occurs after a 'pci_enable_pcie_error_reporting()' call, it
must be undone by a corresponding 'pci_disable_pcie_error_reporting()'
call
Add the missing call in the error handling path of the probe and in the
remove function.
Fixes: b012ee6bfe2a ("mhi: pci_generic: Add PCI error handlers")
