From: Bolarinwa Olayemi Saheed <refactormyself@gmail.com>
pqi_set_pcie_completion_timeout() return PCIBIOS_ error codes which were passed on down the call heirarchy 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.
