[fvm] Prevent duplicate device names

Driver Framework V2 will prevent multiple child devices with the same
name from being bound. FVM names it's child devices after the partition
name and the entry number. When a partition is destroyed, the entry in
FVM is cleared before the child device is removed. Tests that rapidly
destroy and recreate partitions can race with the device being removed
to get multiple child devices with the same name to exist at the same
time.

This change prevents multiple child devices with the same name from
being bound by preventing a FVM entry from being reused while there is
still a device running for the entry.
