[PATCH 2/2] fwu: Gracefully handle missing FWU metadata device

On systems with FWU enabled but without the required DT changes the FWU
metadata device is not found and fwu_boottime_checks() returns an error.
Being an initcall, that non-zero return aborts the boot flow

Return 0 instead so the boot continues. The preceding log_err() still
tells the user that the FWU device could not be found.

We have reached issue where testing team is using the same defconfig
to test both scenarios and difference is in DT itself.
I think it should be quite save to return 0 if any UCLASS_FWU_MDATA driver
is not detected. If there is issue with fwu structure error is correctly
propagated.
