mmc: sdhci-pci: Convert PCIBIOS_* return codes to errnos
commit ebc4fc34eae8ddfbef49f2bdaced1bf4167ef80d upstream.
jmicron_pmos() and sdhci_pci_probe() use pci_{read,write}_config_byte()
that return PCIBIOS_* codes. The return code is then returned as is by
jmicron_probe() and sdhci_pci_probe(). Similarly, the return code is
also returned as is from jmicron_resume(). Both probe and resume
functions should return normal errnos.
Convert PCIBIOS_* returns code using pcibios_err_to_errno() into normal
errno before returning them the fix these issues.
Fixes: 7582041ff3d4 ("mmc: sdhci-pci: fix simple_return.cocci warnings")
Fixes: 45211e215984 ("sdhci: toggle JMicron PMOS setting")
