[RFC v3 0/2] migration: Update error description whenever migration fails

[Tejus GK]

Hi everyone,

Thank you everyone for the reviews, this is the v3 patchset based on the 
reviews received on the previous ones. 

Links to the previous patchsets:
v1: https://lists.gnu.org/archive/html/qemu-devel/2023-05/msg00868.html
v2: https://lists.gnu.org/archive/html/qemu-devel/2023-05/msg01943.html

I've broken this patchset into two parts; the first patch contains fixes
for places in migration.c where the failure reason is not updated.
Compared to the previous patchset, this fixes a few errors existing in  
the last patch and covers a few more places where the failure reason 
isn't updated. 

The second patch, covers places outside of migration.c, which eventually 
lead to a migration failure, along with an error_report() call being 
made, however without an update for the failure reason. I am aware that 
the changes in vmstate.c breaks the build due to a unit-test build 
failing, so I wanted to know the right way to approach this. 

regards,
Tejus
