btrfs: zoned: fix btrfs_can_activate_zone() to support DUP profile

commit 9e1cdf0c354e46e428c0e0cab008abbe81b6013d upstream.

btrfs_can_activate_zone() returns true if at least one device has one zone
available for activation. This is OK for the single profile, but not OK for
DUP profile. We need two zones to create a DUP block group. Fix it by
properly handling the case with the profile flags.
