pcie_speeds() returns PCIBIOS_ error codes from PCIe capability accessors.

PCIBIOS_ error codes have positive values. Passing on these values is
inconsistent with functions which return only a negative value on failure.

Before passing on the return value of PCIe capability accessors, call
pcibios_err_to_errno() to convert any positive PCIBIOS_ error codes to
negative generic error values.
