OvmfPkg/VirtioFsDxe: map "errno" values to EFI_STATUS
The VirtioFsFuseCheckResponse() function dedicates the EFI_DEVICE_ERROR
status code to the case when the Virtio Filesystem device explicitly
returns an error via the "VIRTIO_FS_FUSE_RESPONSE.Error" field.
Said field effectively carries a Linux "errno" value. Introduce a helper
function for mapping "errno" values to (hopefully) reasonable EFI_STATUS
codes. This way we'll be able to propagate "errno" values as EFI_STATUS
return codes along the UEFI call stack -- in some detail anyway.
