common/sfc_efx/base: convert EFX PCIe INTF to MCDI value

Browse Source 
When the driver queries its PCIe interface type via MCDI,
the value from the response is translated to an EFX enum.

When the driver passes this enum value back to any other
MCDI helper, the inverse translation has to be conducted.

Fixes: 1bf9ff57ccb3 ("common/sfc_efx/base: allow getting VNIC MCDI client handles")
