btrfs: zoned: fix zone activation with missing devices
If btrfs_zone_activate() is called with a filesystem that has missing
devices (e.g. a RAID file system mounted in degraded mode) it is accessing
the btrfs_device::zone_info pointer, which will not be set if the device in
question is missing.
Check if the device is present (by checking if it has a valid block
device pointer associated) and if not, skip zone activation for it.
Fixes: f9a912a3c45f ("btrfs: zoned: make zone activation multi stripe capable")
