[PATCH v2 1/3] pci: cleanup failover sanity check

[Laurent Vivier]

Commit a1190ab628 has added a "allow_unplug_during_migration = true" at
the end of the main "if" block, so it is not needed to set it anymore
in the previous checking.

Remove it, to have only sub-ifs that check for needed conditions and exit
if one fails.

Fixes: 4f5b6a05a4e7 ("pci: add option for net failover")
Fixes: a1190ab628c0 ("migration: allow unplug during migration for failover 
devices")
