The return value of API is 0 for success and negative error code for
failure. We'll check if the return value equals to 0.
Also, the MIG_MODE should be CPR_TRANSFER and CPR_EXEC instead
of 2 same bits.

The API usage is aligned with 'hw/vfio/cpr-legacy.c' after these 2
changes.

Fixes: 3ca0a0ab05c ("migration: Use bitset of MigMode instead of variable 
arguments")
