PCI: Replace cxl_error_is_native() with pcie_aer_is_native()

The AER driver includes a CXL support function cxl_error_is_native(). This
function adds no additional value from pcie_aer_is_native().

Simplify the codebase by removing cxl_error_is_native() and replace
occurrences of cxl_error_is_native() with pcie_aer_is_native().
